Describe the solution you'd like

Currently, a user does not have the possibility of setting options for the Semeru Cloud Compiler deployed by OLO (these options are decided by the Operator internally). To facilitate problem determination, as well as fine tuning for the Semeru Cloud Compiler, it would be best if the user can specify additional environment variables for the Semeru Cloud Compiler deployed by OLO.
E.g.

  semeruCloudCompiler:
    enable: true
    replicas: 1
    env:
      - name: _JAVA_OPTIONS
        value: "-Xjit:verbose"
