The `add user` and `enable account` commands create fully privileged administrative users like they did in 2.1. This makes the addition of read-only users backwards compatible. Updated and expanded the documentation on administrative interface users. Added entries into the release notes as well as the upgrading document about relevant changes between 2.1 and 2.2.

Upgrading MariaDB MaxScale from 2.1 to 2.2
This document describes possible issues upgrading MariaDB MaxScale from version 2.1 to 2.2.
For more information about MariaDB MaxScale 2.2, please refer to the ChangeLog.
For a complete list of changes in MaxScale 2.2.0, refer to the MaxScale 2.2.0 Release Notes.
Before starting the upgrade, we recommend you back up your current configuration file.
Administrative Users
The file format for the administrative users used by MaxScale has been
changed. Old style files are automatically upgraded and a backup of the old file is
stored in /var/lib/maxscale/passwd.backup.
Regular Expression Parameters
Modules may now use a built-in regular expression string parameter type instead
of a normal string when accepting patterns. The modules that use the new regex
parameter type are qlafilter and tee. When inputting pattern, enclose the
string in slashes, e.g. match=/^select/ defines the pattern ^select.
