[Bug 1099900] [NEW] rados parsing error with hostnames in mon_host

[David Britton]

Public bug reported:

In /etc/ceph/ceph.conf, if I set hostnames in the mon_host variable and
separate them with spaces, the parsing algorithm breaks down.  The
expectation is that all three of these cases should work.  Once
hostnames are introduced in the mon_host line, spaces are no longer
allowed anywhere or parse errors happen.

Precise is being used, here is the ceph-common package information:

Using IP addresses, spaces as separators:

$ grep mon /etc/ceph/ceph.conf
 mon host = 10.151.12.34:6789 10.245.205.215:6789 10.243.34.22:6789
