Given: 
A list of all the supported Camunda databases, and are used for testing in our CI.

When:
Providing this list to a Jenkins Matrix in our Jenkinsfile.

Then:
The Jenkins Matrix optimizes the generation of all the stages that need to be tested against our DB list.

Note:

• The following jobs need to be tested against all of our supported DBs:
  • Engine-UNIT
  • Engine-UNIT authorizations
  • Webapp-UNIT
  • Webapp-UNIT authorizations
• Each job "instance" needs to use a separate DB instance.
  • E.g.: engine-UNIT-mysql-57 and engine-UNIT-authorizations-mysql-57 need to use separate MySQL-5.7 instances/agents.
