multidelete query parameter not correctly parsed
Look very closely at the query parameters in the URI.
The API says "delete" with no value.
Boto sends the same "delete"
Ruby aws-sdk-v1 sends "delete=" (no value, but explicit "=")
Ceph looks for EXACTLY "delete" as the query parameter.
I think Ceph should be less strict, so that the Ruby aws-sdk-v1 Gem works.
This bug has been present since multi-delete was first introduced in commit 0a1f4a97dab02d951834882985523657dfea7e09, v0.50-158-g0a1f4a9 for bobtail.
