fix: add quotes to connector and source names in java client

[jzaralim]

Description

The functions describeConnector, createConnector, dropConnector and describeSource did not add quotes to the sql commands sent to the rest endpoints, so case sensitive names weren't preserved.

Testing done

updated unit tests, integration test still passes

Reviewer checklist

• [ ] Ensure docs are updated if necessary. (eg. if a user visible feature is being added or changed).
• [ ] Ensure relevant issues are linked (description should include text like "Fixes #")

Hey @jzaralim , this functionality is intentional (as least as of today -- we could choose to explicitly change it if this is undesirable, but I think the change is more complicated than what's in this PR, since if we change the case-sensitivity for these methods then we'll want to change it for all methods for consistency). Users can add quotes themselves before passing the strings to the methods, if they want to preserve case-sensitivity. Seems what we really want is (1) a product-level decision on the desired behavior, and (2) a docs update. WDYT? cc @colinhicks as well

@vcrfxia That makes sense, I agree that this should be documented. I'll close this if the consensus is to keep this behaviour.
