RFE: allow the operator to control which floating ip pool is selected by default when allocating a new floating ip

[Lars Kellogg-Stedman]

There may exist multiple floating ip pools in an OpenStack environment. The operator may prefer that users allocate from a specific pool by default. While this can be partially addresses by documentation, people are terrible at reading things and it would be nice if the operator could control which floating ip network is pre-selected in the "allocate floating ip" dialog.

Ideally this would be something that could be controlled via metadata associated with the network, such as the tagging mechanism.

[Akihiro Motoki (amotoki)]

It sounds reasonable that some floating IP pool is preferred when a deployment has multiple floating IP pools. From my operator experiences, there are cases where some floating IP pool is a preferred route and other pools are optional. In such cases, it sounds reasonable that the preferred pool is pre-selected.
