Apt: add new apt configuration format

This adds an improved apt configuration format that is fully backwards
compatible with previous behavior. This is mostly copied from curtin's
implementation.

It does:
 * clean up and centralizes many of the top level 'apt_*' values that
   previously existed into a single top level 'apt'key.
 * support a 'source' in apt/sources/entry that has only a key
 * documents new features and adds tests.

See the added doc/examples/cloud-config-apt.txt for more information.
