Added REST methods for task and trigger validation that accept JSON body

[rybandrei2014]

What changes are being made and why?

Kestra doesn't provide rest endpoints for validation of task and triggers in JSON format. Endpoint for task/trigger validation /validate/task accepts only YAML body.
Following PR adds two new endpoints:

• /validate/task - endpoint for task validation, accepts JSON body
• /validate/trigger - endpoint for trigger validation, accepts JSON body

Hi @rybandrei2014 ,

Sorry for the late answer, can you also provide unit tests in https://github.com/kestra-io/kestra/blob/develop/webserver/src/test/java/io/kestra/webserver/controllers/api/FlowControllerTest.java

Hi @loicmathieu,

no worries, thanks for your reaction.

I added unit tests for new endpoints.

Thank you

Can you move all your tests data inline in the Java test class so they are more easily found and didn't add too many files.

You can use text blocks to deal with double quotes, for ex:

String task = """
    {
      "id": "task_one",
      "type": "io.kestra.plugin.core.log.Log"
    }
"""

Suggested change

	@ExecuteOn(TaskExecutors.IO)
	// This endpoint is not used by the Kestra UI nor our CLI but is provided for the API users for convenience
	@ExecuteOn(TaskExecutors.IO)

Adding a comment will prevent someone removing the method as not used ;)

Sorry for keeping you waiting and late reply
