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.

Mike Lang 9af7795f34 Add gevent.backdoor as an optional arg to all services 
Backdoor allows the operator to telnet into the given port, and get a python shell
running inside the process, from which you can debug, modify state (eg. set the log level),
or whatever. This is extremely useful for debugging weird states that you encounter randomly
but can't easily reproduce, without restarting the process and needing to wait until it happens again.

Mike Lang 90ccc6d827 backfiller: Track number of successful backfills 
Other stats can come later, but this one is important as it tells us if
a downloader hasn't been doing its job.

Mike Lang b0ded641c3 Add a logging handler which counts logs for prometheus stats 
This isn't as good as having a full centralised logging system, but should
suffice to know if anything funny is happening.

Mike Lang 6815924097 Fix some bugs and linter errors introduced by backfiller 
I ran `pyflakes` on the repo and found these bugs:

```
./common/common.py:289: undefined name 'random'
./downloader/downloader/main.py:7: 'random' imported but unused
./backfiller/backfiller/main.py:150: undefined name 'variant'
./backfiller/backfiller/main.py:158: undefined name 'timedelta'
./backfiller/backfiller/main.py:171: undefined name 'sort'
./backfiller/backfiller/main.py:173: undefined name 'sort'
```
(ok, the "imported but unused" one isn't a bug, but the rest are)

This fixes those, as well as a further issue I saw with sorting of hours.

Iterables are not sortable. As an obvious example, what if your iterable was infinite?
As a result, any attempt to sort an iterable that is not already a friendly type like a list
or tuple will result in an error. We avoid this by coercing to list, fully realising the iterable
and putting it into a form that python will let us sort. It also avoids the nasty side-effect
of mutating the list that gets passed into us, which the caller may not expect. Consider this example:

```
>>> my_hours = ["one", "two", "three"]
>>> print my_hours
["one", "two", "three"]
>>> backfill_node(base_dir, node, stream, variants, hours=my_hours, order='forward')
>>> print my_hours
["one", "three", "two"]
```

Also, one of the linter errors was non-trivial to fix - we were trying to get a list of hours
(which is an api call for a particular variant), but at a time when we weren't dealing with a single
variant. My solution was to get a list of hours for ALL variants, and take the union.
