Create ResellerAdmin role in keystone

Quoting the swift doc:

 Users with the Keystone role defined in reseller_admin_role
 (ResellerAdmin by default) can operate on any account. The auth system
 sets the request environ reseller_request to True if a request is
 coming from an user with this role. This can be used by other
 middlewares.

As this role is not used by any other OpenStack component, it makes
sense to create that role here, and not in the keystone cookbook.

[NavMenu] Don't open in new tab/window

All other barclamps open in the same tab/window, so we should be
consistent here. General rule is that if it's in the same domain, don't
open a new tab/window.

Register endpoints with public name and FQDN when possible

When using SSL, the common name field in the certificates is checked,
and using IP addresses won't work with that.

Internally to the OpenStack setup, it is always fine to use the FQDN
from the node, so we use this in the internal and admin URLs of the
endpoints.

For the public URL, we prefer to use the public name if it is set. If it
it not set, then we use the public FQDN only if SSL is enabled;
otherwise, we prefer the IP address (like before) because we're not 100%
sure that the administrator will have completed a proper DNS setup where
the public FQDN generated by Crowbar will be announced externally.

Note that swift-proxy always uses SSL.
