Add a Scheduler to the project

[karlcow]

We need to add a scheduler to populate the data into the DB which is already there. In #20 we had code. We will recreate a scheduler.

This issue is not about saving needsdiagnosis data into the DB, but just having the scheduler ready and see how it goes.

• [x] Install a scheduler addon - Heroku Scheduler?
• [x] Create a bin/
• [x] Create a minimal script doing something dumb for proof of concept. (see #77 )
• [x] Configure a task in the scheduler

@laghee do you need a scheduler for a less regular task?

I'm asking because https://devcenter.heroku.com/articles/scheduler#scheduling-jobs is pretty basic but would answer the need for a hourly script (needsdiagnosis)

While APScheduler offers more flexibility https://devcenter.heroku.com/articles/clock-processes-python

The difference too is that the simple addon from Heroku is just that. :) Aka no need to code the scheduler. Just add scripts in their UI.

Just added the Heroku Scheduler to webcompat-metrics

in https://devcenter.heroku.com/articles/scheduler

For apps built on other frameworks or languages, another convention is to add a script to bin/ that will perform the task. An example bin/clean-sessions script:

The PR #77 will help to advance our goals for https://github.com/mozilla/webcompat-team-okrs/issues/48

Once the PR #77 has been validated by @laghee I will add the task to the scheduler and we can start discover if our proof of concept is working.

Next step will be #67

[laghee]

I went ahead and merged PR #77 -- on our way to super-cool automated data flow!

[karlcow]

This is working manually at least.

[karlcow]

ok this definitely seems to be working.

[karlcow]

next step is #67
