Initial draft of prometheus-agent (#8785)
* Initial draft of prometheus-agent

This commit introduces a new binary, prometheus-agent, based on the
Grafana Agent code. It runs a WAL-only version of prometheus without the
TSDB, alerting, or rule evaluations. It is intended to be used to
remote_write to Prometheus or another remote_write receiver.

By default, prometheus-agent will listen on port 9095 to not collide
with the prometheus default of 9090.

Truncation of the WAL cooperates on a best-effort case with Remote
Write. Every time the WAL is truncated, the minimum timestamp of data to
truncate is determined by the lowest sent timestamp of all samples
across all remote_write endpoints. This gives loose guarantees that data
from the WAL will not try to be removed until the maximum sample
lifetime passes or remote_write starts functionining.

Make React UI the default, keep old UI under /classic (#8142)
The React app's assets are now served under /assets, while all old
custom web assets (including the ones for console templates) are now
served from /classic/static.

I tested different combinations of --web.external-url and
--web.route-prefix with proxies in front, and I couldn't find a problem
yet with the routing. Console templates also still work.

While migrating old endpoints to /classic, I noticed that /version was
being treated like a lot of the old UI pages, with readiness check
handler in front of it, etc. I kept it in /version and removed that
readiness wrapper, since it doesn't seem to be needed for that endpoint.

Stop CMUX and GRPC servers even with stale connections (#7810)
I have received a recent report for a user which confirms that sometime
the GRPC server does not stop propery.

It appears that there are 2 issues:

1. The cmux server can refuse to stop if there are stale connections.
For that we set the ReadTimeout.
2. The GRPC server graceful stop can never finish.

What this PR avoids is:

```
goroutine 227 [semacquire, 2 minutes]:
sync.runtime_Semacquire(0xc00059a75c)
    /usr/local/go/src/runtime/sema.go:56 +0x42
sync.(*WaitGroup).Wait(0xc00059a75c)
    /usr/local/go/src/sync/waitgroup.go:130 +0x64
google.golang.org/grpc.(*Server).GracefulStop(0xc00059a600)
```

This PR stops the GRPC server after 15s. Related to the go routing dumps
in #6747.

M-map full chunks of Head from disk (#6679)
When appending to the head and a chunk is full it is flushed to the disk and m-mapped (memory mapped) to free up memory

Prom startup now happens in these stages
 - Iterate the m-maped chunks from disk and keep a map of series reference to its slice of mmapped chunks.
- Iterate the WAL as usual. Whenever we create a new series, look for it's mmapped chunks in the map created before and add it to that series.

If a head chunk is corrupted the currpted one and all chunks after that are deleted and the data after the corruption is recovered from the existing WAL which means that a corruption in m-mapped files results in NO data loss.

[Mmaped chunks format](https://github.com/prometheus/prometheus/blob/master/tsdb/docs/format/head_chunks.md)  - main difference is that the chunk for mmaping now also includes series reference because there is no index for mapping series to chunks.
[The block chunks](https://github.com/prometheus/prometheus/blob/master/tsdb/docs/format/chunks.md) are accessed from the index which includes the offsets for the chunks in the chunks file - example - chunks of series ID have offsets 200, 500 etc in the chunk files.
In case of mmaped chunks, the offsets are stored in memory and accessed from that. During WAL replay, these offsets are restored by iterating all m-mapped chunks as stated above by matching the series id present in the chunk header and offset of that chunk in that file.

**Prombench results**

_WAL Replay_

1h Wal reply time
30% less wal reply time - 4m31 vs 3m36
2h Wal reply time
20% less wal reply time - 8m16 vs 7m

_Memory During WAL Replay_

High Churn:
10-15% less RAM -  32gb vs 28gb
20% less RAM after compaction 34gb vs 27gb
No Churn:
20-30% less RAM -  23gb vs 18gb
40% less RAM after compaction 32.5gb vs 20gb

Bartlomiej Plotka 34426766d8 Unify Iterator interfaces. All point to storage now.
This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things.
All todos I added will be fixed in follow up PRs.

* querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged
with storage interface.go. All imports that.
* querier.SeriesIterator replaced by chunkenc.Iterator
* Added chunkenc.Iterator.Seek method and tests for xor implementation (?)
* Since we properly handle SelectParams for Select methods I adjusted min max
based on that. This should help in terms of performance for queries with functions like offset.
* added Seek to deletedIterator and test.
* storage/tsdb was removed as it was only a unnecessary glue with incompatible structs.

No logic was changed, only different source of abstractions, so no need for benchmarks.
