[Autotest] merge cleanup and verify
The objective of this CL is to merge cleanup and verify into a single job to
reduce run time of each test. In existing design, by default, a cleanup job is
scheduled after a test is finished, and a verify job is scheduled before a
test is started. By merging these two jobs together, we are seeing the total
run time of these two jobs is reduced from about 47s to 37s, around 10s saving.
That does not include the saving on scheduler to schedule two jobs, which may
take another 5-10s.
The design is to create a new special task, reset, which runs at the beginning
of a job by default. Verify task is changed to not to run by default before a
job starts. Cleanup job will only be run if a job is scheduled to reboot and
any test failed in that job.
