[TASK] Execute tests via docker

The patch adds a new entry script Build/Script/runTests.sh
that hides away all the complexity of test suite execution
and docker details to execute everything that bamboo performs
locally via docker.

Use Build/Script/runTests.sh -h for an overview of available
options.

Example call to execute all functional tests on postgres DBMS
and sending xdebug output to a local (phpstorm) listening on
port 9000:
Build/Script/runTests.sh -s functional -d postgres -x
