function test cleanup
This function is defined in the base test script for a test, and executes
commands to clean up after the test. Note that Fuego will perform some cleanup
automatically, such as removing the test directory, and any log files or tmp
directories that it created. This function is optional, and is used
to kill outstanding (still-running) processes.
This function, when defined, commonly calls kill_procs
to kill any functions which the test might have left running (for example,
if the test was interrupted by a timeout, or failed in some other way).
This function can also be used for any other post_test processing that is
specific to an individual test. This could include things such as
restoring device configurations, unmounting filesystems, cleaning up other
areas of the filesystem that the test may have affected (outside those
in the test directory or temp directories that Fuego manages).
