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.
