Implement catalogue federation

[florianm]

Implement ckan to ckan harvesting (requires same metadata schema to be used on both ends, depends on #4)

[florianm]

ckan_harvester clashes on "extra" fields with ckanext-scheming. Also throws https://github.com/ckan/ckanext-harvest/issues/151

• CSW server runs as docker container on localhost:8086
• Test WMS successfully harvested into CSW

Next steps:

• Pending new subdomains, publish CSW localhost:8086 to csw.data.wa.gov.au
• Register csw.data.wa.gov.au's GetCapabilities statement
• Run ckan harvester job

ckanext-dcat up and running, presenting the catalogue contents as

• http://catalogue-beta.data.wa.gov.au/catalog.ttl
• http://catalogue-beta.data.wa.gov.au/catalog.rdf
• http://catalogue-beta.data.wa.gov.au/catalog.xml
• http://catalogue-beta.data.wa.gov.au/catalog.jsonld

Individual datasets are available in machine-readable format when appending .n3, .rdf, .ttl, or .xml to the dataset's url.
