Stop swallowing errors when paginating

[seanstory]

Closes #2394

Previously, paginated_api_call would swallow all exceptions (after logging a warning). Now, it raises, them, and let's the caller decide whether to swallow or re-raise them.

• _remote_validation(): re-raises (seems important to fail validation if invalid)
• fetch_attachments(): logs warnings, but does not raise
• fetch_page_blog_documents(): logs warnings, but does not raise
• fetch_spaces(): re-raises (seems important to not skip whole spaces - that should fail the sync)
• search_by_query(): re-raises (seems important to let you know if your advanced sync rules are incorrect)

Also, I took a pass through the file to make sure that we were using exc_info=exception everywhere we were logging about an exception, instead of stuff like f"Exception: {exception}"

Release Note

Improved the Confluence connector by ensuring that Confluence pagination API request errors bubble up when appropriate. This may result in more syncs ending in an error state, but these would not be new errors/issues, they will just be more visible and actionable.
