mononoke/repo_import: add hg sync checker

Browse Source 
Summary:
Related diff: D22816538 (3abc4312af)

In repo_import tool once we move a bookmark to reveal commits to users, we want to check if hg_sync has received the commits. To do this, we extract the largest log id from bookmarks_update_log to compare it with the mutable_counter value related to hg_sync. If the counter value is larger or equal to the log id, we can move the bookmark to the next batch of commits. Otherwise, we sleep, retry fetching the mutable_counter value and compare the two again.
mutable_counters is an sql table that can track bookmarks log update instances with a counter.
This diff adds the functionality to extract the mutable_counters value for hg_sync.

======================
SQL query fix:
In the previous diff (D22816538 (3abc4312af)) we didn't cover the case where we might not get an ID which should return None. This diff fixes this error.
