Mike Lang 71333cf826 backfiller: Only run one manager, not one per channel 
Then treat backfilling each channel just like backfilling each quality.

This is conceptually simpler (only one kind of thing, a (channel, quality))
and has better behaviour when a node is down (we only have one lot of error handling around it).

It also means we aren't asking the database for the same info once per channel,
and cuts down on logging noise.

Mike Lang ff18c7df54 backfiller: Fix issue with tracking metrics after get_nodes() failure 
There isn't an easy, clean way to pass in the DB hostname there,
and neither label is very valuable. Let's just drop it entirely.

Mike Lang 731ef9e2d0 Refactor dockerfiles for more shared layers 
By carefully ensuring most of our dockerfiles are identical in their first few layers,
we only need to build those layers once instead of every time.

In particular, we move installing gevent to before installing common,
so that even when common changes gevent doesn't need to be reinstalled.

This is important because gevent takes ages to install.

Also fixes segment_coverage, which wasn't being installed.

Mike Lang 0e437566aa backfiller: Don't crash on DB errors 
We move all connection handling into get_nodes().
This means that problems connecting won't cause further errors
and cause the application to completely crash.

In turn, this means that the behaviour if the database goes down becomes
"continue backfilling from the nodes we know about" instead of crashing.

Mike Lang f50276bd01 backfiller: Expose recent_cutoff as CLI arg and increase it to 120s default 
In testing, GDQ's stream delay went up over 1min, which caused backfillers to backfill
segments at the same time they were downloaded. We increase the window for now,
and also make it configurable.

Mike Lang 29040a166c backfiller: Allow multiple concurrent segment downloads 
This will signifigantly increase throughput when downloading
large ranges of segments.

The max concurrency is exposed as a cli arg.

We also slightly modify the logged info, so it reports segments downloaded,
not just number of missing segments (which we might skip downloading for various reasons).

Mike Lang 7179fcacec Backfiller: ignore temp segments 
To make this work, we make type a proper segment field.

We also tell get_best_segments to ignore temp segments, since they might go away
before we can actually use them.

Mike Lang f8d10dacdf Audit and fix all usage of dateutil 
We wrap direct dateutil calls to handle two distinct cases:

* `common.dateutil.parse()`: We want to handle arbitrary timestamps including tz info,
then convert them to UTC.

This is used in HLS parsing, and for command line input for backfiller

* `common.dateutil.parse_utc_only()`: We want to only handle UTC timestamps,
but datetime.strptime isn't flexible enough (eg. can't handle missing fractional component).

This is used for restreamer request params.
