In Django 1.10, the old `MIDDLEWARE_CLASSES` style was deprecated and we
should now use `MIDDLEWARE` setting.

This commit includes this move and takes advantage of the new
MiddlewareMixin to help provide compatibility for our custom middleware.

Prior to Django 1.10, user.is_authenticated() was a method.
Since then, compatibility was ensured but this compatibility will be
removed in Django 2.0. This commit thus moves to using the
user.is_authenticated attribute instead.

Migrate to New Middleware style #2662

Use user.is_authenticated as an attribute #2664

Fixes #2668.

During Active Directory activation, we query the Workgroup information
from the AD server using `net ads workgroup`. This normally gets its
parameters from `smb.conf` but we need here to explicitly give the
required server information at the command call given we usually work
with an empty `smb.conf` file at this stage.

This commit switches from using the `-S|--server` flag to the `--realm`
flag as that has proven more robust.

We currently use InfoPipe to fetch the groupname of domain users. While
this works for Active Directory users, this can fail for LDAP users if
these do not belong to a posixAccount group.

This commit simply catches the DBusException thrown in such cases and
logs the event (DEBUG level). The result is a groupname of "null".

Also includes:
- minor Black formatting
- type hints
- import optimization
- minor copyright updates
