Automatic parsing from dashed env vars

[toschneck]

Find a way to map env vars like SAKULI_LOG_FOLDER to the sakuli property sakuli.log.folder automatically.

This will be helpful to manage docker containers from the outside during runtime like in an openshift deployment.

2 Possible ways to go:

• Extend the SpringPropertyLoader so that this kind of environment vars could be also read SakuliPropertyPlaceholderConfigurer
• (alternative) Extend the go wrapper, to do the env parsing: https://github.com/spf13/viper, https://github.com/rickar/props

Example: openshift.sakuli.gitvolume.pod.run.yaml

      volumeMounts:
      - mountPath: /headless/sakuli/testsuite
        name: vol-testsuite
      args:
        - run
        - /headless/sakuli/testsuite/${GIT_TEST_SUITE_PATH}
        - -D
        # must be a writable path
        - sakuli.log.folder=/headless/sakuli/logs
        - -D
        # not needed in openshift environment
        - sakuli.forwarder.gearman.cache.enabled=false

      volumeMounts:
      - mountPath: /headless/sakuli/testsuite
        name: vol-testsuite
      env:
      - name: SAKULI_TEST_SUITE
        value: headless/sakuli/testsuite/${GIT_TEST_SUITE_PATH}
      - name: SAKULI_LOG_FOLDER
        value: $SAKULI_ROOT/logs

Try to read all properties in sakuli-default.properties from the environment. If found, it will overwrite the property value.
