Test support output schema http://standards.iso.org/iso/19115/-3/mdb/2.0 for some servers

Is your feature request related to a problem? Please describe.

Some GeoNetwork servers support newer output schema: http://standards.iso.org/iso/19115/-3/mdb/2.0

e.g. aodn:

https://catalogue.aodn.org.au/geonetwork/srv/eng/csw?service=CSW&version=2.0.2&request=GetRecords&constraintLanguage=FILTER&constraint_language_version=1.1.0&resultType=results&elementsetname=full&outputschema=http%3A%2F%2Fstandards.iso.org%2Fiso%2F19115%2F-3%2Fmdb%2F2.0&typeNames=gmd%3AMD_Metadata&startPosition=1&maxRecords=3

Our default output schema used in the config: http://www.isotc211.org/2005/gmd works. However, some key fields (e.g. mdb:metadataLinkage) won't be available.

We need to:

• write a few test cases for the new output schema: http://standards.iso.org/iso/19115/-3/mdb/2.0
• pave the schema gaps if any
• tested it in the dev cluster

• Old default schema output: https://catalogue.aodn.org.au/geonetwork/srv/eng/csw?service=CSW&version=2.0.2&request=GetRecordById&elementsetname=full&outputschema=http://www.isotc211.org/2005/gmd&id=c317b0fe-02e8-4ff9-96c9-563fd58e82ac
• New schema output: https://catalogue.aodn.org.au/geonetwork/srv/eng/csw?service=CSW&version=2.0.2&request=GetRecordById&elementsetname=full&outputschema=http://standards.iso.org/iso/19115/-3/mdb/2.0&id=c317b0fe-02e8-4ff9-96c9-563fd58e82ac
