* Adapt UI for Prometheus Agent
UI is not my strongest skill, but I'd like to have something minimal for
the initial release of the agent.

I would like to avoid extra API call's to determine if we are running in
Agent Mode, so I think we could use this approach.
This is a bootstrap of #9612

* 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.

* Move remote read handler to remote package.
This follows the pattern I started with the remote write handler. The api/v1 package is getting pretty cluttered. Moving code to other packages helps reduce this size and also makes it reusable - eg Cortex doesn't do streaming remote writes yet, and will very soon.

- Remove unrelated changes
- Refactor code out of the API module - that is already getting pretty crowded.
- Don't track reference for AddFast in remote write. This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series. For now, its easier and safer to always use the 'slow' path.
- Return 400 on out of order samples.
- Use remote.DecodeWriteRequest in the remote write adapters.
- Put this behing the 'remote-write-server' feature flag
- Add some (very) basic docs.
- Used named return & add test for commit error propagation

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.

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.

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.
