* fix federate endpoint panic

Signed-off-by: yeya24 <yb532204897@gmail.com>

* Fixed all cases of not ready TSDB being wrongly handled.

* Fixed issue for federation.
* Ensured this will never happen again thanks to interfaces
* Fixes same issue for stats.
* Added tests for readiness.
* Fixed bug in stats. It was:
   status.MaxTime = db.Head().MaxTime()
   status.MinTime = db.Head().MaxTime()

Bartlomiej Plotka 34426766d8 Unify Iterator interfaces. All point to storage now.
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.
