lib/protoparser/prometheus: move streamparser to subpackage (#3814) 
`lib/protoparser/prometheus` is used by various applications,
such as `app/vmalert`. The recent change to the
`lib/protoparser/prometheus` package introduced a new dependency
of `lib/writeconcurrencylimiter` which exposes some metrics.
Because of the dependency, now all applications which have this
dependency also expose these metrics.

Creating a new `lib/protoparser/prometheus/stream` package helps
to remove these metrics from apps which use `lib/protoparser/prometheus`
as dependency.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3761

discover/ec2: bump API version (#3702) 
Switch to the actual API version `2016-11-15`,
since the old version doesn't provide access to all
the fields which implementation expects.
For example, old API missing `zone_id` field
in `DescribeAvailabilityZonesResponse` response.

lib/promscrape: limit number of sent stale series at once (#3686) 
Stale series are sent when there is a difference between current
and previous scrapes. Those series which disappeared in the current scrape
are marked as stale and sent to the remote storage.

Sending stale series requires memory allocation and in case when too many
series disappear in the same it could result in noticeable memory spike.
For example, re-deploy of a big fleet of service can result into
excessive memory usage for vmagent, because all the series with old
pod name will be marked as stale and sent to the remote write storage.

This change limits the number of stale series which can be sent at once,
so memory usage remains steady.
