Move result teardown to loops

[carmocca]

What does this PR do?

See title.

This was added to the LoggerConnector first because the loops weren't finished yet.

The Loops base implementation has been changed so teardown is not called every run call as we don't want to teardown every time run finishes for the smaller granularity loops.

Part of #7938
Includes #8250
