The Context was only used to obtain a reference to the CASCache
and set the unused cas_directory field.

The fake context did not set the cache quota, triggering an error. With
CASCache now separate from ArtifactCache, we can instantiate a CASCache
without context.

The default values are in userconfig.yaml, together with the
documentation. The default values should not be duplicated in
_context.py.

_context.py: Drop duplicated default values for user configuration
