This function has been vestigial for a long time. Remove it and move
its remaining functionality into the constructor.
Update users to the new interface (this is remarkably easy and
simplifies the code).

Instead of specifying an IP address in ceph.conf like
[global]
cluster_addr = 10.1.2.3
you can now avoid the node-specific configuration and just say
[global]
cluster_network = 10.1.2.0/24
The *_network variables can also take a whitespace-separated list of
networks, to be checked in that order:
[global]
cluster_network = 10.1.2.0/24 192.168.42.192/26
