Abstract class that defines the interface of an include handler.
Implements a handler where every configuration file should
contain a dictionary as the base type with and 'includes'

The includes can be specified in two ways, as a string
containing the relative path from the current file or as a
dictionary. The dictionary should have a 'file' key, containing
the relative path to the include file and optionally a 'repo'
key, containing the key of the repository. If the 'repo' key is
missing the value of the 'file' key is treated the same as if
just a string was defined, meaning the path is relative to the
current config file otherwise its relative to the repository path.
The includes are read and merged depth first from top to buttom.
