[Enhancement] Log cancel pipeline only once

[ZiheLiu]

Why I'm doing:

Decrease log of begin to cancel operators. Some operators will take lots of time to cancel, which causes PipelineDriver::cancel_operators is called multiple times when it is expired.

What I'm doing:

Only log begin to cancel operators once for a pipeline driver.
