Display security group name in security-group-rule-list

It is useful to display security group name rather than its id
for security_group_id and source_group_id.

Also add '--no-nameconv' option to disable conversion from
security group id to its name. When security-group-rule-list is executed
by admin user it is likely more than one groups have same name.
This option is useful for such cases.
