Jason Tedor b54a9e9c83 Introduce translog generation rolling ...

This commit introduces a maximum size for a translog generation and
automatically rolls the translog when a generation exceeds the threshold
into a new generation. This threshold is configurable per index and
defaults to sixty-four megabytes. We introduce this constraint as
sequence numbers will require keeping around more than the current
generation (to ensure that we can rollback to the global
checkpoint). Without keeping the size of generations under control,
having to keep old generations around could consume excessive disk
space. A follow-up will enable commits to trim previous generations
based on the global checkpoint.
