add base_service_manipulation test

Summary:
Not much to say, pretty much just implements the test case using
some commands I dug up that give us handy 0/1 exit statuses.
The assert_script_run function (from testapi) simply runs a
command/script and passes or fails based on the exit status;
we use a handy bash-ism when we *want* the exit status to be 1.

Test Plan: Run the test and check that it passes (properly).
