Prepare for classification of comments #4094
Description
There are some tasks that need to be done to prepare for comment models:
### Tasks
- [x] Create a function to `get_comment` from Bugzilla using `comment_id`
- [x] Create a `comment_classifier` script that classifies using `comment_id`
- [x] Create a function in `http_service` to classify comments using a list of `comment_ids`
- [ ] Create a comment classification job.
- [ ] Create a function to classify a single or batch comments. (in `http_service/bugbug_http/app.py`)
This issue would also be a good place to discuss on the best way to run models on comments:
With the proposed task list above, it was considering to classify comments independently of bugs by using comment_ids.
I thought it would be wise to separate this work from #3994 to minimise the amount of reviews needed to land the model.
