be6777bc86 Reduce overhead of the mutations for SELECTs (v2) 
SELECTs are affected by the mutations, since it tries to apply them on
fly, and scanning over existing mutations can take significant amount of
time (for simple queries, i.e. count())

And also even after mutation had been finished, it still a problem,
because mutations are not removed instantly.

So instead introduce an atomic counter alter_conversions_mutations, that
is incremented for new mutations and decremented once mutation
finished/killed, that way once the mutation finished they will not
affect queries.

Here are some numbers for non-RENAME mutations:

    rmt vanilla w/o mutations | queries: 3693, QPS: 494.813
    rmt vanilla w/ mutations  | queries: 2190, QPS: 388.256
    rmt patched w/o mutations | queries: 3168, QPS: 620.061
    rmt patched w/ mutations  | queries: 3155, QPS: 614.424
    mt vanilla w/o mutations  | queries: 3498, QPS: 656.399
    mt vanilla w/ mutations   | queries: 3821, QPS: 600.425
    mt patched w/o mutations  | queries: 5732, QPS: 745.585
    mt patched w/ mutations   | queries: 4719, QPS: 715.034
