enables connectivity mode and deploys stretch cluster with arbiter mon node
Actions Performed:
1. Disables the automatic crush map update
2. Collects the OSD daemons in the cluster and split them into 2 sites.
3. If add capacity is selected, only half of the OSD's will be added to various sites initially.
4. Adds the stretch rule into crush map.
5. Adding monitors into the 2 sites.
6. Create a replicated pool and deploy stretch mode.
7. Create a test pool, write some data and perform add capacity. ( add osd nodes into two sites )
8. Check for the bump in election epochs throughout.
9. Check the acting set in PG for 4 OSD's. 2 from each site.
