Subject: Add script to bisect test failures with ttcn3 and docker

With this script you can now use docker ttcn3 test results to bisect a
regression and find the offending commit.

Use like this from the osmo-* git repository:
$ git bisect start <bad-rev> <good-rev>
$ git bisect run ~/scm/osmo/docker-playground/osmo-bisect.sh <component-to-test> <testcase>
e.g.:
$ git bisect run ~/scm/osmo/docker-playground/osmo-bisect.sh bsc BSC_Tests.TC_ho_in_fail_no_detect
