mgmt/glusterd: Store arbiter-count and restore it

Problem:
1) Glusterd doesn't remember about arbiter information of replica volume in
   store.  When glusterd goes down and comes backup, arbiter volumes will
   become replica volumes.

2) Glusterd doesn't import/export arbiter information to/from the other peers.

3) Volume info doesn't show any arbiter count in the output.

Fix:
1) Persist arbiter information in glusterd-store
2) Import/Export arbiter information of the volume
3) Change volume info output to show arbiter count.
