Fixes#295 on login pw upgrade. This adds support for SSHA512 to be imported at the request of @colbyprior, and adds a delayed action queue so that events can be run after-the-fact so that authentication does not need to exist under the write path.
Implements #127 and #125. This adds domain_info support, and spn types and generation. It also correctly handles domain renaming, and has tooling to support this. It "should" work on an upgrade, due to the correct bump of index version, but I plan to test this from a backup of my production instance soon.
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.
