[Pywps-dev] unify PyWPS and pycsw configurations

[Tom Kralidis]

Hi all: the PyWPS and pycsw configurations are quite similar:

PyWPS: https://github.com/PyWPS/pywps-4-demo/blob/master/pywps.cfg
pycsw: https://github.com/geopython/pycsw/blob/master/default-sample.cfg

Given the similarities and that both PyWPS and pycsw are heading into
major releases (PyWPS 4, pycsw 2.0), it's a great time to work on unifying
these for common objects to align.

Proposal:

- unify server sections
- move PyWPS [wps] and [provider] sections into a single section called
  [metadata:main]

The benefit here would be a single config for both installs.  This would not
limit each project from their own specific additional config sections
or options,
but would make the ones they share in common consistent and clear.

Thoughts?
