RFE Replace the existing default subnetpool configuration options with an admin-only API

[John Davidge]

During the Liberty cycle a consensus was reached within the neutron l3 subteam that the existing method for setting default subnetpools in neutron.conf was not working as well as it could.

As an admin, I want to be able to set the default subnetpool via the neutron API, and without the need to restart services for the change to take effect.

The proposed solution is to add a new boolean 'is_default' field to the subnetpool object. This field will be False by default, configurable only by the admin, and initially can only be True for one subnetpool in each IP family. Future work could allow multiple defaults once RBAC is implemented for subnetpools.

This change will greatly improve the default subnetpool workflow for admins, as well as exposing information about the default subnetpool to users.

    Replace subnetpool config options with admin-only API

    This patch adds a new boolean 'is_default' property to subnetpools. This
    allows the admin to set the default v4/v6 subnetpools via the API rather
    than the existing neutron.conf options - which are deprecated by this patch.

    Only one subnetpool per IP family can be set to default.
