Ability to manage groups and group membership

[simonw]

This should list all groups, and members of those groups, and show which groups have dynamic configuration and what that configuration is.

• /-/acl/groups could list all groups
• /-/acl/groups/xxx could be a page for that group

It should not be possible to delete a group that is defined as a dynamic group in plugin configuration.

Group membership should have an audit log.

[simonw]

The group membership audit log will be separate from the acl_audit log, but we could still present a chronological timeline that combines the two tables using a UNION.

[simonw]

So far:

The manage group page will be a whole lot more interesting with the audit log - could include the date each member was added and who by.

Still missing:

• [x] Tests
• [x] Documentation
• [x] Indication that a group is a dynamic group
• [x] Link to manage groups from menu

[simonw]

Dynamic groups should not allow manual adding at all.

Need to be able to create and delete groups.
