* removed experiment-compute and integrated all components into opendc-compute

* updated workflow gradle file

* removed unneeded code

This change adds to the experiment base in OpenDC a provisioning tool to
help setup the experimental environment in a reproducible manner.

The experimental environment can be defined in terms of *provisioning
steps* which manage the allocation, configuration, and clean-up of all
resources necessary for the experiments.

The provisioning steps are executed sequentially, so in case of dependencies,
the steps need to be ordered correctly.

This change adds a new module called opendc-experiments-base which will
provide a base for doing experiments with OpenDC. The initial feature we
introduce is the service registry which acts as DNS for services to
register during experimentation.
