cluster/ec: Add self-heal-daemon command handlers
This patch introduces the changes required in ec xlator to handle index/full heal. Index healer threads: Ec xlator start an index healer thread per local brick. This thread keeps waking up every minute to check if there are any files to be healed based on the indices kept in index directory. Whenever child_up event comes, then also this index healer thread wakes up and crawls the indices and triggers heal. When self-heal-daemon is disabled on this particular volume then the healer thread keeps waiting until it is enabled again to perform heals. Full healer threads: Ec xlator starts a full healer thread for the local subvolume provided by glusterd to perform full crawl on the directory hierarchy to perform heals. Once the crawl completes the thread exits if no more full heals are issued. Changed xl-op prefix GF_AFR_OP to GF_SHD_OP to make it more generic.
