NIFI-12255 refactor PutElasticsearchRecord and PutElasticsearchJson relationships to be more consistent with other processors

Summary

NIFI-12255 refactor PutElasticsearchRecord and PutElasticsearchJson relationships to be more consistent with other processors

Additionally:

• added ability to unit test migrateRelationships for processor refactoring
• addressed issue with StandardTestRunner#migrateProperties where some properties may be null
• addressed some warnings in MockProcessContext and StandardTestRunner implementations, improving some logging for easier test failure diagnostics

Breaking Change: addition of the successfull relationship to PutElasticsearchJson will require the connection to be added to a downstream processor (or terminated within the processor config). Relationship has been added for consistency with PutElasticsearchRecord, along with original (automatically renamed from success) and errors.

RE the migration testing, I discussed this with @markap14 at the time. I find some issues with the property mock processing, so fixed that (I'll have to reverse engineer what the problem was now, if more details are needed).

Adding the relationship mocking is something that could be separated out, although at the time it helped me confirm the updates I wanted to make and I thought it might be helpful for others in the future. It does, of course, increase this PR a bit though. Happy to create a separate jira ticket and either link it here (to reflect the additional change), or try to separate out the changes if people think it's necessary

I've rebased from latest main to address merge conflicts.

Let me know your thoughts on previous comments @exceptionfactory.

Rebased against latest main to refactor changed into new nifi-extension-bundles module

@ChrisSamo632 Thanks for rebasing and also leveraging migrate properties!
