@pvgenuchten can you rebase? |

alternative would be to use owslib.wms130.__build_getmap_request (but challenge to replace bbox array for {bbox})

or better/also to use xyz (both not in catinterop yet, see OSGeo/Cat-Interop#42)

Overview
populate links in record.geojson for common link types using the suggested templated approach
Related Issue / Discussion
in #814 I raised the question how record.geojson links are modelled from the pycsw datamodel for the typical wms/wfs protocols. This PR presents a suggestion for implementation
Additional Information
A lot of conventions are adopted and discussions are taking place on how one can model a link between a iso19139 metadata record and a specific layer in ows capabilities. In general 2 approaches are common, append on the metadatalink to the service the &layers is parameter to detail the relevant layer, others adopted the &layers={onlineresource.name} convention. This PR supports both cases (but will cause problems if none of the 2 are implemented)
To identify the type of link, the catinterop identifier of the protocol is assumed in link[type], else the link will be treated as a generic link
