cluster/ec: Provide an option to enable/disable eager lock

Problem: If a fop takes lock, and completes its operation,
it waits for 1 second before releasing the lock. However,
If ec find any lock contention within this time period,
it release the lock immediately before time expires. As we
take lock on first brick, for few operations, like read, it
might happen that discovery of lock contention might take
long time and can degrades the performance.

Solution: Provide an option to enable/disable eager lock.
If eager lock is disabled, lock will be released as soon
as fop completes.

gluster v set <VOLUME NAME> disperse.eager-lock on
gluster v set <VOLUME NAME> disperse.eager-lock off
