[TASK] Run tests on new bamboo infrastructure

A new bamboo agent infrastructure has been deployed that
significantly changes how tests are executed: The agent
docker containers are now "stupid" and no longer bundle
specific php versions or daemons. Instead, they can run
own containers to start needed daemons for specific jobs
and execute needed php commands in ad-hoc containers that
provide the required php version.
Daemons needed for single jobs are defined in a
docker-compose.yml file provided by core itself.
This docker-compose.yml file can not be used directly for
local test execution since it has to fiddle quite a bit
with docker volume mounts, networks and executing users
that is specific to the bamboo environment.
However, another yml file can be added later to ease local
test execution in a similar way.
The patch rewrites the bamboo plan pre-merge and nightly
specs of core master to use the new infrastructure and brings
a couple of minor changes to tests that rely on a running
memcached or redis to retrieve the daemon host from an
environment variable.
There will be separated patche for older core versions.
