Description

We are now regularly recommending this as a multi-site configuration for customers with low latency links,
but we do not actually test that it works. We want to start adding some scenario tests, and this seems a
likely one:

1. create a cluster with three monitors and six osds and a topology that says M+3OSD in each of two sites, with a quorum monitor in a third site.
2. create two pools: one two in site A, one in site B, and the other its complement.
3. test failure of an OSD in either pool in either site (correct recovery)
4. test total failure of either site, recovery, and re-recovery after return
5. test failure of the quorum monitor (no big deal), and reintegration after return
