Previously it was allocating millions of chunks, all containing the
same 250 samples. Above some ratio of CPU performance to available
memory, the benchmark cannot run.
Make 250 a const and just allocate one chunk which we iterate
repeatedly till we reach the benchmark count.

Add cleanup of the lockfile when the db is cleanly closed
The metric describes the status of the lockfile on startup
0: Already existed
1: Did not exist
-1: Disabled
Therefore, if the min value over time of this metric is 0, that means that executions have exited uncleanly
We can then use that metric to have a much lower threshold on the crashlooping alert:
If the metric exists and it has been zero, two restarts is enough to trigger the alarm
If it does not exist (old prom version for example), the current five restarts threshold remains

Snappy cannot encode records larger than ~3.7 GB and will panic if an
encoding is attempted. Check to make sure that the record is smaller
than this before encoding.
In the future, we could improve this behavior to still compress large

panic for users with very large single scrape targets.

* Add Seek() implementation for memSafeIterator
Previously, calling memSafeIterator.Seek() would call the Seek() method
on its embedded iterator. This was causing the embedded iterator and the
memSafeIterator to get out of sync because when the embedded Seek()
moved to the next element of the embedded iterator, memSafeIterator
didn't "know" about it. memSafeIterator has to "know" when the embedded
iterator has moved to be able to work out when it should be reading from
its buffer rather than the embedded iterator.
Used same logic as for xorIterator.Seek() (which in runtime is used as
the embedded iterator) - return false if the iterator has an error and
try to move to next element if the required time hasn't been reached, or
if no elements have been read yet. The memSafeIterator.Next() method is
being called so memSafeIterator.i is always accurate.

This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.
