Set up tests againsts 2020 reference implementation

[berezovskyi]

Main tasks

• Use old AM, CM, RM configs as a reference.
  • AM
  • CM
  • RM
• Set up GH Actions to test weekly. Blocked by Deploy to DockerHub oslc-op/refimpl#60 needed to run reference implementation servers in containers along the CI container.

Wishlist

• Test more representations, e.g. Turtle and JSON-LD
• Use (new) Lyo Client to make OSLC requests instead of using Apache HttpClient (actually, a nasty mix of the new 4.x client and the old 3.x Commons client in one project).
• Label error messages with CC-### identifiers from specs.
• Test for OSLC 3 features, e.g. CORS/CSP, .well-known, and LDP.

Housekeeping

• Upgrade JUnit from 4.8 to 4.13
• Update Jena from 2.x to 3.16 as used by the latest Lyo (but we may consider using this repo to test our newer Jena versions, e.g. 4.x)
• Merge in the TRS test codebase into one module?
