* Unregister remote write queue manager specific metrics when stopping the
queue manager.
* Use DeleteLabelValues instead of Unregister to remove queue and watcher
related metrics when we stop them. Create those metrics in the structs
start functions rather than in their constructors because of the
ordering of creation, start, and stop in remote storage ApplyConfig.
* Add setMetrics function to WAL watcher so we can set
the watchers metrics in it's Start function, but not
have to call Start in some tests (causes data race).

From the documentation:
> The default HTTP client's Transport may not
> reuse HTTP/1.x "keep-alive" TCP connections if the Body is
> not read to completion and closed.
This effectively enable keep-alive for the fixed requests.

The documentation for Context states that this is just as good:
// If Done is not yet closed, Err returns nil.
// If Done is closed, Err returns a non-nil error

Now that we're not losing the scrape cache across failed
scrape, a scrape that continually failed but had varying
series or metadata (e.g. timestamps in metric names,
plus hitting smaple_limit) would grow the cache indefinitely.
Add some code to catch that, and flush the cache anyway.

The goal is to remove almost all references to the
golang.org/x/net/context package.
github.com/gogo/protobuf => v1.2.1
google.golang.org/grpc => v1.19.1
github.com/grpc-ecosystem/grpc-gateway => v1.18.5
It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux
because of [1] which fixes#3909 incidentally.

Like `promtool check config <path/to/foo.yaml>`, which resolves relative
paths inside foo.yaml to be relative to `path/to`, this now makes
`promtool test rules <path/to/test.yaml>` do the same thing.
