Summary:
We retried if a db connection was lost when executing a query, but not when
establishing a connection. I've seen a lot of failures establishing connections
in our install (they go away when retrying), so this diff retries when
establishing connections, and logs when we retry.
Test Plan:
- Loaded phabricator in a sandbox
- Temporarily added a check in the try block to throw if there were still
retries (to test logging, retry logic)
