Train models on TaskCluster whenever their corresponding files are modified

[suhaibmujahid]

Whenever a file in the bugbug/models directory is modified, we could have a task to train the corresponding model.

For example, if a new Pull Request is modifying the bugbug/models/defect.py file, the task should train the defect model:

python -m scripts.trainer defect

As a first step, we could build a script to do this "manually" and not on PRs (doing it on PRs might be a bit complicated, as we need to run the whole pipeline to be able to train a model)

It would be nice if we could trigger TaskCluster training using the same script with an optional argument.

Example:

python -m scripts.trainer defect --taskcluster

As suggested by Marco, we could use TaskCluster API to replicate creating a task like https://community-tc.services.mozilla.com/tasks/RpQqfhKgT6GTlvOmK9i_vw/runs/0
