radosgw/swift wildcard acl elements
In swift, it's possible to do wildcard acl grants, such as test:*, :tester, *., or those forms using hex id instead of name.
In hammer, these elements apparently get filtered out as invalid names.
In master, these elements can be stored, but I don't see code to interpret them so I believe they would simply be ignored.
There appear to be users out in the wild who would like to use this feature.
