performance/io-threads: Provide option to turn off least-priority
RCA:
In cases when self-heal is in progress, self-heal fops are starved
because of least-priority. This affects other fops with conflicting
inode, entry locks with self-heal.
Fix:
This patch provides configuring enable/disable of least-priority.
Additional changes:
Moved RCHECKSUM fop to low instead of least because it will still
affect the performance of other fops if RCHECKSUM is in LEAST
priority.
Tests:
Tested that the enabling/disabling of fops is working fine.
Tested that RCHECKSUM fop priority is assigned LOW when
least-priority is disabled.
