This commit only improves logging whenever ENOSPC (No space on disk)
or EDQUOT (Quota limit exceeded) is returned by glusterfs
Also, added methods to:
- get filename from file descriptor
- log with rate limit
Caveat: Although raising DiskFileNoSpace results in object-server
returning HTTPInsufficientStorage[507] correctly, the swift proxy-server
invokes "best_response" method that returns [503] to the user.
When write-behind translator is turned on in glusterfs, it may set
errno to EIO instead of ENOSPC/EDQUOT. This is documented in BZ 986812
BUG: 985862, 985253, 1020724
