Tag mechanism supports network, subnet, port, subnetpool router resources only. This patch allow tag mechanism to support resources with standard attribute. Two old extenions are kept because of backward compatibility. They will be removed in Queens release. APIImpact: Tag is supported by resources with standard attribute DocImpact: allow users to set tags on resources with standard attribute Change-Id: Id7bb13b5beb58c313eea94ca03835d3daf5c94bc Closes-Bug: #1682775
