since golang 1.12 no special handling is required for file.Sync()

Testing that createBlock creates blocks that can be opened.
and checking the os.RemoveAll for errors will catch errors for un-closed files under windows.
Many missing .Close() calls were added for fixing failing os.RemoveAll

`if ds[i].meta.MinTime < t0 || ds[i].meta.MaxTime > t0+tr `, ds[i].meta.MinTime is always larger or equal to t0, so no need for this check.
`ulid.Parse` only checks if the length is 26. So changed to using `ulid.ParseStrict` to also check the validity of ulid.

Added methods needed to retain data based on a byte limitation rather than time. Limitation is only applied if the flag is set (defaults to 0). Both blocks that are older than the retention period and the blocks that make the size of the storage too large are removed.
2 new metrics for keeping track of the size of the local storage folder and the amount of times data has been deleted because the size restriction was exceeded.

This change also uses the latest staticcheck version which comes with
new verifications, hence some clean up in the code.

This reverts commit 98fe30438c.
After some discussion, it was concluded that we want the full
`prometheus_tsdb_...` prefix hardcoded in the library.

Blocks are half-open intervals [a, b), while all other intervals
(chunks, head, ...) are closed intervals [a, b].
Make that distinction explicit by defining `OverlapsClosedInterval()`
methods for blocks and chunks, and using them in place of the more
generic `intervalOverlap()` function.
This change also fixes `db.Querier()` and `db.Delete()`, which could
previously return one extraneous block at the end of the specified
interval.

This is based on my experience while debugging https://github.com/prometheus/prometheus/issues/3943.
I needed to deduct few things, and all that would be just bit easier with these two logs:
- new block's ULID on each compaction.
- actual list of Blocks (ulid + time range) on Prometheus startup (easy to log that while repairing blocks).
We don't really need blocks that takes part in compaction - that can be deducted easily based on time ranges of blocks we have currently in system.
What do you think?
