Specified crush-ruleset-name is required to exist, implicit creation is
going to happen only if crush-ruleset-name wasn't specified on the
command line. While at it, pool-name is very much a required param.

Prior to this commit, the Network Configuration Reference guide and
Troubleshooting guide recommended opening a number of ports that were
unique to the number of daemons that we ran.
This doesn't really cover all use cases. Users can easily restart
daemons in ways that cause the daemons to bind to higher ports. This
leads to OSDs or MDSs binding to ports that are firewalled.
Update the Network Configuration Reference guide and Troubleshooting
guides to simply recommend that users open all the ports between 6800
and 7300 on their OSDs and MDSs.

To actually get the benefit of writeback caching, qemu must be
aware of it so it pases flushes to rbd. Since hammer rbd caching
is enabled by default, so add the nova option to make qemu aware
of it.
