Can the team please weigh on unifying task/test log name that includes test output in DW?

Tasks that are executed in Beaker with restraint have a standard log name `taskout.log`
TFT executed tests have the name output.txt, testing-farm publishes them as `testout.log`

kcidb_tools is publishing the logs using the same names as the test runners use.

Different log names create some confusion when we add regexes for issues that are observed in both Testing Farm and Beaker environments.
We could workaround it and match both logs names with `(task|test)out\.log`
But it may be easier to unify the log name instead of remembering of the different file names.
