Implements #6 - create, modify and delete. These are the raw/lowlevel db commands which are really useful for administrators. They aren't intended for normal day to day use though.
This also adds a basic getting started, fixes a missing privilege, adds support for reseting another accounts password, and for server side password generation.
It's likely I'm going to reformat some of the current REST api though to use our higher level internal types.
Partially Implements #6 - add ability for accounts to self set password. This is good for now, as I get closer to a trial radius deployment, but I think I'm finding the rest api probably needs a better plan at this point, as well as probably the way we do the proto and the communication needs some more thoughts too.
This adds the fundamentals of the basic IDM layout. It contains the needed design document, and is designed such that the default admins while powerful, still have some limits upon them.
