🎉 Source greenhouse: added identification of accessible streams for API keys with limited permissions

[midavadim]

What

API key can be granted with permissions to any combinations of endpoints.
User who uses that API key might don't know a list of endpoints he has access to.

Solution: programmatically try to read each supported stream and process only 'accessible' streams during connector setup and sync

Added comments.

Nice!

Can we add a sentence in the greenhouse source documentation highlighting that the connector will only process streams it has access to.
