Right now Queue Manager metrics are registered when the metrics struct
is created, which happens before a changed queue is shutdown and the old
metrics are unregistered. In the case of named queues or updates to
external labels the apply config will panic due to duplicate metrics.
Instead, register the metrics as part of starting the queue as we always
guarantee that Stop will be called before a new Start.

* Pending Samples metric includes samples in channel
The pending samples metric should also include samples waiting in the
channels to be sent to provide a more accurate measure. In addition,
make sure that the pending samples is reset to 0 anytime a queue is
started as we remake all of the shards at that time.

jQuery prior to 3.4.0 is affected by an Object.prototype pollution
vulnerability (CVE-2019-11358). Even though our code doesn't seem to be
vulnerable to the issue, lets upgrade to the latest jQuery release so we
don't have to bother.

* Fixed nits introduced by https://github.com/prometheus/prometheus/pull/7334
* Added ChunkQueryable implementation to fanout and readyStorage.
* Added more comments.
* Changed NewVerticalChunkSeriesMerger to CompactingChunkSeriesMerger, removed tiny interface by reusing VerticalSeriesMergeFunc for overlapping algorithm for
both chunks and series, for both querying and compacting (!) + made sure duplicates are merged.
* Added ErrChunkSeriesSet
* Added Samples interface for seamless []promb.Sample to []tsdbutil.Sample conversion.
* Deprecating non chunks serieset based StreamChunkedReadResponses, added chunk one.
* Improved tests.
* Split remote client into Write (old storage) and read.
* Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved
all config based options to sampleAndChunkQueryableClient to aboid boilerplate.
In next commit: Changes for TSDB.

use ?wait=10m will give results as fast as usual when data is changing
but will perform far less requests when services do not change.
On large infrastructure, this will reduce quite a lot the number of
qps on Consul servers while having the same performance for freshness
of results.

Previously `max` results stopped reading from results in tests
prematurely, as it stopped when `max` number of items were received from
the channel instead of `max` number of unique target groups received.
This caused flaky tests where the same target group was received
multiple times, as Kubernetes informers may emit the same event multiple
times.
Before this patch, running this test repeatedly failed eventually. After
this patch I have run the test many thousand times without failure.
```bash
go test -run TestEndpointsDiscoveryNamespaces -count 1000 -test.v
```
