* Updated the memory usage of Tasks. Still in Progress.

* Merged Task and ServiceTask -> Currently not fully working!!!

* Fixed bugs that made the merger between Task and ServiceTask not work well.

* Updated jdk version for Dockerfile

* Removed ServiceFlavor.java and Task.kt

* Updated all package versions including kotlin. Updated all web-server tests to run.

* Changed the java version of the tests. OpenDC now only supports java 19.

* small update

* test update

* new update

* updated docker version to 19

* updated docker version to 19

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

* updated workflow gradle file

* removed unneeded code

This change integrates the classes from the old
`opendc-compute-workload` module into the `opendc-experiments-compute`
module. This new module contains helper classes for setting up
experiments with the OpenDC compute service.

This change removes the dependency on the OpenTelemetry SDK. Instead,
we'll only expose metrics via the OpenTelemetry API in the future via
adapter classes.

This change removes the OpenTelemetry integration from the OpenDC
Compute modules. Previously, we chose to integrate OpenTelemetry to
provide a unified way to report metrics to the users.

Although this worked as expected, the overhead of the OpenTelemetry when
collecting metrics during simulation was considerable and lacked more
optimization opportunities (other than providing a separate API
implementation). Furthermore, since we were tied to OpenTelemetry's SDK
implementation, we experienced issues with throttling and registering
multiple instruments.

We will instead use another approach, where we expose the core metrics
in OpenDC via specialized interfaces (see the commits before) such that
access is fast and can be done without having to interface with
OpenTelemetry. In addition, we will provide an adapter to that is able
to forward these metrics to OpenTelemetry implementations, so we can
still integrate with the wider ecosystem.

This change updates the `ParquetDataWriter` class to not use the
`parquet-avro` library for exporting experiment data, but instead to use
the low-level APIs to directly write the data in Parquet format.

This change updates the Gradle build configuration to ensure that all
library modules (that will be published) use testing and are included in
coverage reports. This should ensure the public modules remain well
tested.

This change updates the compute support library to load the VM
interference model via the OpenDC trace library, which provides a
generic interface for reading interference models associated with
workload traces.

This change removes the opendc-platform module from the project. This
module represented a Java platform which was previously used for sharing
a set of dependency versions between subprojects. However, with the
version catalogue that was added by Gradle, we currently do not use the
platform anymore.
