cluster/afr: Provide option to set readdir-size in entry-self-heal
Problem: Entry self-heal does lookups on all the entries that are read in readdir. More the size of readdir more number of lookups happen in parallel. It is observed that it leads to HUGE cpu spikes rendering everything else on the system unusable. Fix: Provided the option self-heal-readdir-size to configure the size. Default value is at 1KB. Tests: Checked that the readdirs are happening with the configured value in entry-self-heal.
