[adwk67]

Description

Related to #618

Most changes in this PR are due to the fact that the API has changed and both old and new versions need to be available for the tests. Code changes can be summarised as:

• adding a condition for the start commands
• adding a condition for new env-vars
• minor change to logging definition

N.B. this PR does not cover updates to OPA-Auth (covered separately).

Sorry if I missed it, but it looks like the supported-version.adoc is missing the 3.0.1 (experimental) addition
