cluster/afr: Make data selfheal trigger to be configurable.
By default, lookup triggers data self-heal but that is not the preferred way
of operating replicated volumes. We would like the data self heals to be
triggered in open instead.
Number of back-ground self-heals allowed is 16 and lookups block until
self-heal is completed. We want to prevent blocking in fops. We can not make
lookups independent of self-heal frames because when there are gfid conflicts
the decision of which file is correct is determined in self-heal phase.
So in afr, lookup self-heal is going to guarantee name space consistency
and open/fd fops will take responsibility for data consistency, these
are non blocking. The user needs to set the option cluster.data-self-heal
"open" for this behavior.
