9c4235532e Fix compaction selection after creating new heads 
This fixes the case where between block creations no compaction
plans are ran. We were not compacting anything in these
cases since the on creation the most recent head block always had
a high timestamp of 0.

f1ae239c20 Persist the right MaxTime when snapshotting 
This is because we cut a new block from where the snapshotted block ends
if we restore from backups and highTimestamp would be where we should be
 starting from.

3410559c1b Compact head block early 
Let older head blocks be compacted once the newest once has samples at
50% of its total range. This allows the memory of the compacted blocks
to be released and garbage collected before a new head block gets
created. Thereby the number of head blocks is 1 or 2 instead of 2 or 3
and memory spikes are reduced.

Fix race condition for 2 appenders having same ts 
Race:
Suppose we have 100 existing series inside a HeadBlock.
Now we open two appenders in two routines A1, A2 and append 30 new series and
60 new series respectively with some common series.

Both try to commit at the same time and the following happens in the given order:

A2 executes createSeries()
A1 executes createSeries() (with its common series referencing the ids from A2)
A1 persists its newlabels, samples
A2 persists its newlabels, samples

Now when reading it back, we read A1's samples which reference A2's id and
thereby fail.
