ceph: use kernel DNS resolver
Change ceph_parse_ips to take either names given as IP addresses or standard hostnames (e.g. localhost). The DNS lookup is done using the dns_resolver facility similar to its use in AFS, NFS, and CIFS. This patch defines CONFIG_CEPH_LIB_USE_DNS_RESOLVER that controls if this feature is on or off.
