Configuration: Removed merge_using_priority_specificity

Browse Source 
This had moved to now be done by plugin cache so it has been removed
from wlauto.core.configuration.configuration and any referenced to it
have been changed to use plugin cache instead.

"""
WA configuration can come from various sources of increasing priority, as well
as being specified in a generic and specific manner (e.g. ``device_config``
and ``nexus10`` respectivly). WA has two rules for the priority of configuration:
- Configuration from higher priority sources overrides configuration from
lower priority sources.
- More specific configuration overrides less specific configuration.
There is a situation where these two rules come into conflict. When a generic
configuration is given in config source of high priority and a specific
configuration is given in a config source of lower priority. In this situation
it is not possible to know the end users intention and WA will error.
:param generic_name: The name of the generic configuration e.g ``device_config``
:param specific_name: The name of the specific configuration used, e.g ``nexus10``
:param cfg_point: A dict of ``ConfigurationPoint``s to be used when merging configuration.
keys=config point name, values=config point
:rtype: A fully merged and validated configuration in the form of a obj_dict.
