* Revert "v7.12.0 release"
This reverts commit 073723cb4d41187f839fbb46565d109293fa22d7.
* set version to v7.13.0-SNAPSHOT
* update samples
* update doc
* Upgrade erlang-server code generation and fix is_authorized crashes
* Introduce structured logging
* Improve general formatting
* Update generated files
* Enable erlang server on CI
* Add echo-server testing to CI
* Require OTP27 explicitly in the generated rebar.config file
* Rework handler and API
With this work, json validation becomes optional, fully implemented in
the `_api` module as it was before, but without being forcibly called by
the `_handler`. It is instead left as optional for the user to take
advantage of the exposed callbacks. Jesse also chooses draft-06 as a
default, but these can be chosen manually by the user too, as long as
jesse implements them.
`_handler` also becomes lighter, it now handles all mime types
transparently by forwarding to a user-given module that must implement
`accept_callback/4` and `provide_callback/4` as described in the
`_logic_handler` callbacks. These will simply be the return values of
cowboy_rest's `content_types_accepted` and `content_types_provided`
respectively, and should simply comply with their defined APIs. They
only get two parameters extending the behaviour, so that the user-given
callback can pattern-match on them: the path prefix of the logic
handler, and the operationID of the call.
* Fix return types for provide_callbacks
* Upgrade jesse to incur no dependencies
The less dependencies the built code requires the better.
* Fix dialyzer errors in the generated code
* Apply stronger dialyzer checks
