Hello All,

<tl;dr>
I would like to propose some new ACLs in Gerrit for the openstack-charms project:

- openstack-core-charms
- ceph-charms
- network-charms
- stable-maintenance
</tl;dr>

With an increasing focus split among the openstack-charmers team, I'm observing that people are focused on more specific subsets of the charms, and would like to propose that new ACLs are created to allow us to recognize that officially. I've chosen the breakdown above as it aligns neatly with where the focus lines are at this point, letting developers work on their specific focus areas.

This proposal would not reduce permissions for anybody who is currently a core on the openstack-charms project and, in fact, future subteam core members could aspire to full openstack-charmers core as well. Ideally, this approach will let us escalate developers to "core" developers for the subteam(s) where they have demonstrated the expertise we expect in a core-charmer. It also allows a more gradual escalation to being a core in the openstack-charms project, making it a progression rather than a single destination.

As a related addition, I'm appending to this proposal the creation of a stable-maintenance ACL which would allow members to manage backports without a full core-charmer grant.
