Subject: [PATCH] Add dump command to print out swagger JSON. (#1537) (#1540)

* Add dump command to print out swagger JSON.

Command outputs to stdout, so can be redirected to a file.
Pretty prints output by default.
--no-pretty can be passed to remove whitespace from json output if it does not need to be human readable

* Update for styleci corrections

* Fix CS and add type hint

* REbase + Updates to documentation of dump command.

* Remove defaultName - config file specifies this
Add return value to dump command

* Update for OA3

* Add a test case

* update command name

* Fix the tests
