Fixes https://github.com/prometheus/common/issues/36
Move logic handling this into the labels package,
so all the cases are handled in one place and we're
less likely to have this come up again.

The desired shards calculation now properly keeps track of the rate of
pending samples, and uses the previously unused integralAccumulator to
adjust for missing information in the desired shards calculation.
Also, configure more capacity for each shard. The default 10 capacity
causes shards to block on each other while
sending remote requests. Default to a 500 sample capacity and explain in
the documentation that having more capacity will help throughput.

* Check for duplicate label names in remote read
Also add test to confirm that #5731 is fixed
* Use subtests in TestValidateLabelsAndMetricName
* Really check that expectedErr matches err

The counter is only increased when tsdb.Open() is called which
Prometheus does only once in its lifetime (when it initializes). If the
corruption can't be recovered, tsdb.Open() returns an error and
Prometheus exits. Hence the metric is either 0 (no corruption) or 1
(corruption detected and repaired). If the latter, the alert isn't
actionable and the only way to resolve it is to restart Prometheus which
would reset the counter.

* Fix context for the showWarning function
If the difference between the current time on a client and time on a server is quite big, Prometheus tries to show a related warning in UI on the Graph tab. But in the code, an incorrect context is used to invoke this method. As a result, an error is showed in the web developer console and the whole page stop working at all. This commit fixes the context.

* Added query logging for prometheus.
Options added:
1) active.queries.filepath: Filename where queries will be recorded
2) active.queries.filesize: Size of the file where queries will be recorded.
Functionality added:
All active queries are now logged in a file. If prometheus crashes unexpectedly, these queries are also printed out on stdout in the rerun.
Queries are written concurrently to an mmaped file, and removed once they are done. Their positions in the file are reused. They are written in json format. However, due to dynamic nature of application, the json has an extra comma after the last query, and is missing an ending ']'. There may also null bytes in the tail of file.
