Series() will fetch all the metadata for a series,
even if it's going to be filtered later due to time ranges.
For 1M series we save ~1.1s if you only needed some of the data, but take an
extra ~.2s if you did want everything.

During the dev Summit 2019/2, there was a consensus to mark stale PR
after 60 days.
This change is adding the stale bot configuration required for this.
The stale bot has already access to the Prometheus organization. It
does _not_ comment and does _not_ close the stale pull request. It just
adds a label 'stale'.
This is already done in the collectd_exporter repository and there it
works as expected.

Previously it could return error if RemoteAddr didn't
have correct format, but since this field has no specified
format, that was little too strict.

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.
