Openstack application credentials support
Hi,
I am trying to use Jclouds to access an openstack swift container using the
application credentials. Is that supported in 2.5.0 version? Below is the
code sample I used and the error message I got. I can a similar question in
StackOverflow[1] as well

Re: Openstack application credentials support
Posted by DImuthu Upeksha <di...@apache.org>.
Seems like V3AuthenticationApi does not have an implementation for access
key authentication so the invocation routes to the base interface which
does not have any HTTP annotation. I implemented the missing feature and it
works for my openstack setup. Here is the commit history for my fork [2].
Please let me know if this is the correct approach and if so, I can send a
PR
