cinder returns wrong "href" in volumes/detail repsonse.
The correct href should be something like this: http://1.1.1.1/volume/
however it's now something like this: http://1.1.1.1/volum/
aka. the 'volume' misses 'e'
below is an example on cinder master：

============================================================================
I did a quick search and nothing interesting showed up, so I think this could be related to any operation in the backend that cut the path to modify it or something. I've never seen something like this with LVM/NFS/RBD so far so definitely need more investigation.
