Add a priorityColor property to the maniphest conduit endpoint
Summary:
I added a getTaskPriorityColor function to the ManiphestTaskPriority class which returns the color set in the maniphest config for the given priority.
This is in preparation for a change to arcanist which will allow it to display the priority color (if it is a supported color) upon running arc tasks.
Fixed some linting issues
Test Plan:
Invoke the maniphest.info method from conduit and ensure that:
- The priorityColor property is given in the json
- the priorityColor property is set correctly
