Moving to TaskCluster component...

There are many functions in mozci.py that do not have equivalent TaskCluster function [1] (e.g determine_trigger_objective)

I've been experimenting with the idea that the developer could use its own credentials to schedule tasks, however, there are some difficulties with treeherder scopes and routes. See thread [1]

I spoke with dustin and we agreed that I go back to the idea that pulse_actions would have its own set of credentials to do the scheduling.

The script that shows the problem is in here [3]. You won't be able to schedule a Linux64 TC with your temporary credentials.

2:44 PM <armenzg> dustin: I am thinking of going back to the idea that pulse_actions can schedule a task on Treeherder that would schedule the graph it needs to
2:44 PM <armenzg> rather than experimenting with the idea that a user would do the scheduling
2:44 PM <dustin> ok
2:44 PM <armenzg> there are too many rough edges
2:45 PM <armenzg> you agreed too easily :)
2:45 PM <armenzg> haha

Some of the original issues are fixed.
In any case, we've fixed enough.
We can file more bugs for new features.
