merge: Simplify OpenDC deployment process

This pull request attempts to simplify the deployment process necessary for 
deploying OpenDC locally or using Docker. There was currently not a clear 
and simple way to deploy OpenDC locally, yet the Docker-based deployment
was also out-of-sync.

## Implementation Notes :hammer_and_pick:

* Address several bugs in the OpenDC web runner
* Fix dependency related issues
* Rename `opendc-web-api` to `opendc-web-server`
* Create a local distribution of `opendc-web-server`.
* Fix Docker deployment
* Update deployment guide

## External Dependencies :four_leaf_clover:

* Quarkus 2.11.1
* `jandex-gradle-plugin` 0.13.2

## Breaking API Changes :warning:

* `TraceFormat.installedProviders` has been changed to `TraceFormat.getInstalledProviders`. 
     The list of installed providers is now not cached at first access, but queried every time the
      method is invoked and its results depend on the caller context (e.g., context class loader).
* `OpenDCRunner` now requires a `JobManager` as constructor argument, which can be 
     constructed as follows: `JobManager.create(client)`
* `opendc-web-api` is now renamed to `opendc-web-server`.
