[1.x] add a script to run bwc test (#889)

This script is used to run bwc tests on a remote cluster.
It will first pull opensearch-dashboards-functional-test
repo in a tmp folder. Then move the required cypress tests
in and run the bwc tests.

partically solved:
opensearch-project/opensearch-build#705

backport PR:
#879
