* Append sparse histograms into the Head block

* Add AtHistogram() to Iterator interface. Make HistoChunk conform to Chunk interface.

* integer types and timestamp separation
1) unify types to int64. as suggested by beorn. we want to support
counters going down (resets) even if we plan to create new chunks for
now, in that case
2) histogram type doesn't know its own timestamp. include it separately
in appending and iteration

* correction: count and zeroCount to remain unsigned
to make api more resilient and that's what we use in protobuf anyway

* temp hack. Ganesh will fix

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.
