[FLINK-9638][E2E Tests] Add helper script to run single test

This commit adds a helper script `run-single-test.sh` that allows you to run
a single test in the context of the text runner.

This provides you with
* Setup of ENV variables
* cleanup after test
* Nicer output

Usage: ./run-single-test.sh <path-to-test-script> [<arg1> <arg2> ...]

This closes #6197.
