integrate systest 0.8.4 changes
Incorporate profile and execution-wide time traps
cluster-management needs a slightly longer time trap
rha_test_utils:start_rabbit/1 should only block/wait if the rpc call succeeds
a few debugging/shell targets that have assisted with the systest 0.8.4 upgrade
Remove the debug target from the makefile

Since debugging via an escript does *not* appear to work, at
least with the common_test runner - which is our preferred means
of executing test suites.
Provide a bit more information about new systest features
ensure we're setting exit_on_eof correctly
Let it crash. And also assert the result of stop_app.
All control_action()s should return ok.
Revert 0944e8b4d2b1, very bad idea since many tests test that control_action() can fail.
rationalise profiles and resources
point kill-multi profile to correct resources
temporary release-branch integration; update README
do not use rabbit/hare/bunny as test node names
Missed variable renaming; tweak the README
generate logging output (including html) directly beneath cwd
generate surefire test reports under ./logs
Added tag rabbitmq_v3_1_0 for changeset f30b649f3b76
add a target just for 'ci'
