Move code out of __init__ and into conf.py module

This allows us to use __init__.py to store __version__ and other
metadata strings and be reused in local documentation and setup.py
to shore a single version file.

The problem with having code in __init__.py is that the code will
be executed even if all the documentation code wants to pull is the
metadata variable.

Initial Commit of Sphinx Config project

Creates a lfdocs-conf package that is pip installable.

The minimal conf.yaml consists of only a project_cfg configuration
with the name of the project eg opendaylight, opnfv, lfdocs:

   ---
   project_cfg: lfdocs

Limitations:

intersphinx_mapping is not currently mappable via yaml due to
it being a complex data set of a tuple + data type (None). Projects
can override this by setting it in their local conf.py or accept the
defaults provided by the lfdocs-conf project.
