[autotest] Add retry to tko/db.commit
suite.py uses RetryingTKO for querying test results, however TKO class does not
use RPC to call get_job_test_statuses_from_db. It is a direct call to db.
In that method, db.connect, db.select are both retried, but not db.commit.
This change adds retry to db.commit.
