To instrument Task manager layer,

Start span can be added in TaskManager.register() method here

I am not sure this is a simple as that:

• TaskManager#register is an entry point, probably make sense to capture the parent span here
• TaskManager#unregister is one of the way task could marked as completed
• TaskManager#cancel is another way task could marked as completed (but cancelled)

May be there are other things I am missing.

These are good starting points. We can get to know more once we start diving deep.
