settings allow processing valid results of LAVA jobs that had an Infrastructure
error. In the test job page of a build, a user can now choose to cancel a job that
is submitted but not yet fetched, also sending this cancel action to job backend.

This is a bug fix release:

In case the job is still in the queue or is in progress, fetch() raises
TemporaryFetchIssue from within block that catches FetchIssue. Since
TemporaryFetchIssue derives from FetchIssue, the exception is
immediately consumed and fetch_attempts counter is increased. This leads
to maxing out fetch_counter for jobs that stay in the queue for a long
time. This patch removes the exception and instead returns from the
fetch() function without an error. This doesn't result in increasing
fetch_attempt counter.
