[pve-devel] [RFC pve-cluster] Prefer name key from corosync config for nodename

Use the name subkey from the cmap keys by default, if not set
fallback to the ring0_addr.
This fixes some issues when we move the corosync communication to
a different network and use an specific address or an new hostname
for that. Withouth this patch the nodename in the .members special
file changes together with ring0_addr, which can result in quite a
few problems (e.g.: in the ha-manager).
This allows also to separate the webinterface traffic from corosync.
