After executing "freezer-scheduler register" we face problem that
all shards failed in elasticsearch (ES).
If we use number of replicas "0" according to ES documentation
for one node installation then this issue disappeared.
After "first use" of freezer tool cloud engineer can add
additional ES nodes to cluster and fine tune this value
in configuration file.
