JC: Add plugin parser functionality to JC Filter Plugin (#6043)
* Add plugin parser functionality to JC Filter Plugin
The parse function was added in jc v1.18.0 which allows plugin parsers to be used. This change will try the new API if available, else fallback to the old API so there is no change in behavior.
* remove whitespace from blank line
* Add changelog fragment for JC plugin parser support
* add .yml extension to file name
* Formatting
* add period at end
(cherry picked from commit c168f9c3be)
