xl: Rewrite auto-healing and implement auto new-disk healer (#8114)

Browse Source 
The new auto healing model selects one node always responsible
for auto-healing the whole cluster, erasure set by erasure set.
If that node dies, another node will be elected as a leading
operator to perform healing.

This code also adds a goroutine which checks each 10 minutes
if there are any new unformatted disks and performs its healing
in that case, only the erasure set which has the new disk will
be healed.
