merge: Improve discovery of interference models (#76)

This pull request intends to improve discovery of interference models. Previously, interference models were not tied to the workload trace, meaning they had to be resolved separately from the workload trace. In reality, the interference model is always tied to the particular workload trace.

With this pull request, we integrate the interference model into the `odcvm` trace format and make it available through the `opendc-trace` library. This has as additional benefit that we can support different interference formats in the future using the same API.

Furthermore, this change allows us to ship the interference model with the workload traces and resolve them automatically in the future using some form of package manager.

## Implementation Notes :hammer_and_pick:

* Incorporate interference model in trace format 
* Load interference model via trace library
* Move conventions into separate package 

## External Dependencies :four_leaf_clover:

* N/A

## Breaking API Changes :warning:

* `VmInterferenceModelReader` has been removed from `opendc-compute-workload`
* Table and column conventions have been moved in `org.opendc.trace.conv` package
