ceph in scenario004 is in _ERR state stuck creating pools

[Giulio Fidente]

In scenario002 we do not deploy MDS and RGW, we create 5 pools and configure a default PG num to 32, totalling 160 PGs which fits within the 200 PGs allowed with a single OSD.

In scenario004 instead we need 9 pools, PGs count needs to be lowered further.

    Lower Ceph PGs count in scenario004

    Each OSD can only host maximum 200 PGs, in scenario004 we create 9
    pools to enable MDS/Manila and RGW so we need to lower the PGs
    count further, compared to scenario001.

    Also lowers the values in low-memory-usage.yaml environment file.
