Log info about task instance clearing/marking as succcess/failure

[ephraimbuddy]

When a task is cleared or marked as failed/successful, we do not have much information other than that the state of the task instance has been externally set to restarting, succes or failed.

This PR adds information about this clearing/marking as success or failed in the log so that users can know exactly what happened.

To make this work, I had to introduce session to TaskContextLogger as without it, when the log is sent, the task instance fails.

@ephraimbuddy would it be helpful to also log the user that performed the clear/delete action?

I don't think it will be possible but I will check.
