commit cloud forwardfiller: add a test to exercise the flow

Summary:
Building on the previous two commits, this adds a test which performs the following steps:
- does an infintiepush push to a Mercurial server
- looks into the `forwardfillerqueue`
- runs commitcloud forwardfiller's `fill-one` to replay the bundle to Mononoke
- verifies that this action causes the commit to appear in Mononoke

As this test uses `getdb.sh` from Mercurial test suite, it needs to be whitelisted from network blackholing (Note: we whitelist mononoke tests, which run with `--mysql` automatically, but this one is different, so we need to add it manually. See bottom diff of the stack for why we don't use `--mysql` and ephemeral shards here).
