Further Elixir Client Improvements (#12775)
* Further Elixir Client Improvements

Resolves #12731 and is the completion of the work that I started with
#12751.

The changes here are extensive and likely resolve an issue that I have
seen with the Ory SDK (ory/sdk#194). I have also been unable to run the
integration suite for Elixir as I am (trying) to run everything in
Docker (`./run-in-docker.sh`) as I *do not* have a suitable Java
development environment set up, and do not do enough Java work to really
justify it.

- Updated the README for Elixir projects. Aside from some improved
  readability of the template by use of link references instead of
  inline links, I have also fixed the examples:

  - The `deps` example should have been putting a version constraint
    related to `appVersion`.

  - The `config` example should have been using `packageName` instead of
    `appName`. This particular issue repeats.

- In all Elixir files:

  - Changed the function `@docs` formatting:

    - changed the ehading level for `Parameters` and `Returns` to h3
      (`###` instead of `##`). This will make somewhat better looking
      documentation that does not over-emphasize these details (which
      are *not* documented in a normal Elixir way, but this is somewhat
      to be expected with a code generator.) It may be desirable, after
      testing, to change this to `h4` instead of `h3`.

    - Put parameter names and most return types in in-line code blocks
      (`` `hello` ``).

    - Put return types, when there are multiple types, in a Markdown
      list.

  - Fixed a lot of the spacing. Most files will be *closer* to Elixir
    standard formatting than they were. Because of the limitations of
    Mustache, it is still recommended that people who generate Elixir
    clients run `mix format` at least once on their codebase.

- `api.mustache`:

  - Removed an awkward function pipeline call. If we specified at least
    Elixir 1.12 (something that I do not recommend as we have recently
    jumped from requiring Elixir 1.6 to Elixir 1.10), there is a better
    way to specify this now with `Kernel.then/2`. In the meantime,
    assigning the constructed request structure to a variable and then
    making a separate pipeline for the request execution and handling
    makes for *much* easier to read generated code.

  - Fixed the extra space issue with `evaluate_response` call tuple
    values; `{{=<% %>=}}` changes the tag types, so this change is
    intentional.

- In `config.exs.mustache`, `runtime.exs.mustache`, `mix.exs.mustache`,
  and `connection.ex.mustache`, use `packageName` instead of `appName`
  for configuration specification. If `packageName` and `appName`
  differed, we would end up with cases like ory/sdk#194.

- `connection.ex.mustache` has been almost entirely rewritten. The
  changes started in order to eliminate a `@doc` compile-time warning,
  but shifted to remove the old way of building Tesla client structs
  with `use Tesla`. It works, but is no longer the recommended way of
  building Tesla clients.

  - The *recommended* way of building a Tesla Client would now be
    `Tesla.client(Connection.middleware(), Connection.adapter())`.

  - Exposed both `Connection.adapter/0` and `Connection.middleware/1`
    for use. `Connection.middleware/1` has special handling for the
    cases where OAuth2 or HTTP Basic Auth are defined in the
    application, but do not currently handle any other auth methods.

- `deserializer.ex.mustache` has mostly been reformatted. There are
  things that I do not like about it (I do not like pipelines with one
  line), and I have expanded one function capture into an anonymous
  function for readability.

- `request_builder.ex.mustache` has been updated with better
  function and parameter descriptions and names. Please note that if
  `request |> method(:delete) |> method(:post)` is supposed to produce
  a `POST` operation, we will need to change from `Map.put_new/3` to
  `Map.put/3`.

  - Reordered `evaluate_response/2` so that it is the function documented,
    and made `decode/2` and `response_mapping/3` private functions. As
    far as I can tell, I have *not* changed the functionality.

* Address issues found in code review

- The example dependency code in the README had dropped the opening
  brace for the tuple. This has been resolved.

- The default formatting of the API pipelines has been adjusted to
  minimize possible changes from `mix format`.

Improved Elixir Code Generation (#12751)
* Bump the minimum version of Elixir supported

The previous minimum version of Elixir is several years EOL.

The current minimum version of Elixir is also EOL, but is the minimum
version required to support some upcoming changes to the config
templates.

* Bump the minimum version fo Tesla

Keep the dependencies up to date

* Add a default .formatter.exs

* Add two Elixir-specific mustache lambdas

- The `atom` lambda results in the proper quoting of an atom depending
  on the safe contents of the atom text, per the Elixir language
  specification. That is, `{{#atom}}foo{{/atom}}` will be turned into
  `:foo` and `{{#atom}foo.bar{{/atom}}` will be turned into
  `:"foo.bar"`.

- The `env_var` lambda results in the treatment of the identifier
  provided being capitalized as an environment variable would be.
  `{{#env_var}}apiVersion{{/env_var}}` would become `ENV_VAR`.

* Use modern Elixir configuration

- This includes runtime configuration
- It depends on the `env_var` lambda.

* Fix a Language Server Warning

This change is *optional*, but removes a LS warning that was raised.

* Regenerated openapi_petstore for Elixir

* Add ex_doc as a default dependency

Fixes #12484

* Refine the regular expression for atoms

The original regex incorrectly matched `123Number` (unquoted atoms
cannot begin with numbers) and would incorrectly quote atoms ending in
`?` or `!`. Through testing with `iex`, it also turns out that the atom
`:-` is legal.

The following atoms will now not be quoted that would have been
incorrectly quoted:

- `:-`
- `:declawed?`
- `:neutered!`

The following atoms will be quoted that were incorrectly unquoted:

- `:"123Number"`

* Improve regex (again), remove files not generated

- The previous commit resulted in a number of warnings that were still
  present and so I played with the regular expression. This did not
  solve the problem, but the resulting regular expression is *much*
  better than the previous one, so I'm keeping it.

- The problem was that the configuration (`bin/configs/elixir.yaml`) is
  generated using a 3.0 input spec:

  ```yaml
  inputSpec: modules/openapi-generator/src/test/resources/3_0/petstore-with-fake-endpoints-models-for-testing.yaml
  ```

  Which means that there were 16 files committed which were no longer
  being generated. When I tested with the 2.0 input spec:

  ```yaml
  inputSpec: modules/openapi-generator/src/test/resources/2_0/petstore-with-fake-endpoints-models-for-testing.yaml
  ```

  The files were generated again. I *believe* that the correct change
  here is to switch back to the 2.0 input spec, as it tests more code
  generation, but I wanted to check in before I did this.

  The following files are deleted:

  - `elixir/lib/openapi_petstore/model/additional_properties_any_type.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_array.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_boolean.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_integer.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_number.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_object.ex`
  - `elixir/lib/openapi_petstore/model/additional_properties_string.ex`
  - `elixir/lib/openapi_petstore/model/big_cat.ex`
  - `elixir/lib/openapi_petstore/model/big_cat_all_of.ex`
  - `elixir/lib/openapi_petstore/model/inline_response_default.ex`
  - `elixir/lib/openapi_petstore/model/special_model_name.ex`
  - `elixir/lib/openapi_petstore/model/type_holder_default.ex`
  - `elixir/lib/openapi_petstore/model/type_holder_example.ex`
  - `elixir/lib/openapi_petstore/model/xml_item.ex`
  - `elixir/pom.xml`
  - `elixir/test/pet_test.exs`

  In the interim, I have removed those files from the commit.
