Fixes incorrect json output for 'openstack server show -f json'.
The security group json output groups all the json as one
for e.g. "security_groups": "name='group1'\nname='group2'"
The correct output should be
"security_groups" : [{"name" : "group1"}, {"name" : "group2"}]
properties and volumes_attached fields also has similar issue.

There was a problem that the '-image-property' option, which can be used
to create an instance, did not work as intended.

I found that there were two problems with this option.

First, I cannot select an image as its metadata.

The second is that when there are multiple images available, the desired
image may not be selected depending on the situation.

This patch solves these two problems.

I wrote the test case with these two problems considered together.

Keystone let's users remove role assignments that reference non-existent
users and groups. This is nice when keystone backs to an identity store
like LDAP and users or groups are removed.

Previously, openstackclient would validate the user and group existed in
keystone before sending the request to delete the role assignment. This
commit updates the code to bypass that validation so that users can use
IDs to forcibly cleanup role assignments.
