merge: Add provisioning tool for experiments (#104)

This pull request implements a new tool to help provision and manage the 
experimental environment.

## Implementation Notes :hammer_and_pick:

* Add service registry for cloud services 
* Add provisioning tool for experiments
* Add provisioning step for workflow service 
* Add provisioners for FaaS service 
* Use experiment base for Capelin experiments
* Use experiment base for web runner
* Integrate compute workload classes
* Remove Topology interface 

## Breaking API Changes :warning:

* Removal of the `opendc-compute-workload`, `opendc-faas-workload`, 
   and `opendc-workflow-workload` modules. These are now located 
   inside `opendc-experiments`
* Removal of `ComputeServiceHelper`. Use `Provisioner` to provision 
   a `ComputeService`.
