merge: Clean up compute service (v1)

This pull request is one in a series of changes that attempt to clean up the 
warts of the OpenDC Compute Service. These changes should make the
API more robust for future developments.

## Implementation Notes :hammer_and_pick:

* Do not suspend in compute API
* Expose state directly to clients
* Do not split interface and implementation

## External Dependencies :four_leaf_clover:

* N/A

## Breaking API Changes :warning:

* The methods of `ComputeClient` do not have the suspend modifier anymore.
* Changes to the classes of `ComputeClient` are now immediately visible on the server side.
   It is not necessary to call `refresh` anymore.
* `ComputeService` must be constructed via its builder class now.
