comment out to speed up tests

* overhaul pistache templates

* fix function signature in model-source
return type now aligns with definition in model-header

* use default keyword for destructors

* generate pistache samples

* move bin/configs/other/cpp-pistache-server-cpp-pistache.yaml to bin/configs/cpp-pistache-server-cpp-pistache.yaml

* Only generate validation body if necessary

* generate pistache samples

 ### PR checklist
-
+ 
 - [ ] Read the [contribution guidelines](https://github.com/openapitools/openapi-generator/blob/master/CONTRIBUTING.md).
-- [ ] If contributing template-only or documentation-only changes which will change sample output, [build the project](https://github.com/OpenAPITools/openapi-generator#14---build-projects) beforehand.
-- [ ] Run the shell script `./bin/generate-samples.sh`to update all Petstore samples related to your fix. This is important, as CI jobs will verify _all_ generator outputs of your HEAD commit as it would merge with master. These must match the expectations made by your contribution. You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example `./bin/generate-samples.sh bin/config/java*`. For Windows users, please run the script in [Git BASH](https://gitforwindows.org/).
-- [ ] File the PR against the [correct branch](https://github.com/OpenAPITools/openapi-generator/wiki/Git-Branches): `master`
-- [ ] Copy the [technical committee](https://github.com/openapitools/openapi-generator/#62---openapi-generator-technical-committee) to review the pull request if your PR is targeting a particular programming language.
+- [ ] Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
+- [ ] Run the following to [build the project](https://github.com/OpenAPITools/openapi-generator#14---build-projects) and update samples:
+  ```
+  ./mvnw clean package 
+  ./bin/generate-samples.sh
+  ./bin/utils/export_docs_generators.sh
+  ``` 
+  Commit all changed files. 
+  This is important, as CI jobs will verify _all_ generator outputs of your HEAD commit as it would merge with master.

 To test the templates, please perform the following:
-- Update the Petstore sample by running the shell scripts under `bin` and `bin/openapi3` folder. For example, run `./bin/python-petstore.sh` and `./bin/openapi3/python-petstore.sh` to update the Python PetStore API client under [`samples/client/petstore/python`](https://github.com/openapitools/openapi-generator/tree/master/samples/client/petstore/python) and [`samples/openapi3/client/petstore/python`](https://github.com/openapitools/openapi-generator/tree/master/samples/openapi3/client/petstore/python). For Windows, the batch files can be found under `bin\windows` folder. (If you find that there are new files generated or unexpected changes as a result of the update, that's not unusual as the test cases are added to the OpenAPI spec from time to time. If you've questions or concerns, please open a ticket to start a discussion)
-- During development it can be helpful to quickly regenerate the samples without recompiling all of openapi-generator, e.g. when you have only updated the mustache templates. This can be done by passing the `-t` parameter: `./bin/python-petstore.sh -t modules/openapi-generator/src/main/resources/python`.
-- Run the tests in the sample folder using maven `mvn integration-test -rf :<artifactId>`, e.g. open a shell in `samples/client/petstore/python`, run `mvn integration-test -rf :PythonPetstoreClientTests`. The artifactId of the project can be found in the pom.xml file. (some languages may not contain unit testing for Petstore and we're looking for contribution from the community to implement those tests)
