UI - Control the timeouts on a task / custom task

[tlawrie]

Is your request related to a problem? Please describe.
Currently all tasks timeout after the default 90 minutes with no ability to provide an override / custom value

Describe the solution you'd like
Ability to provide a custom timeout either at the global level or specifically at the Custom Task level.

Describe the benefits or justification for this request
This will allow tasks that may need longer to perform to have that time, or if you know a task will timeout quickly, to efficiently have that happen.
