tests: remove dropin test

This determines the pass/fail of a test based on the execution
of a command.  This is the predecessor of Avocado SIMPLE tests,
and as such, can be removed in favor of the former.

1. Modify the repeat time from 300 to 100 about with_repetition test.
   Repeat 300 times takes too long time.
2. Modify the repeat time from 3 to 1 about not repetition test.
   Repeat hotplug and unplug can be covered by with_repetition test.
3. Limited the with_shutdown.after_plug only with_plug,
   When test without_plug, this case is no needed.
