Provide docker images for ACTS (was ACTS-249)

Original author Christian Gumpert @cgumpert

ACTS currently has only few dependencies. However, plugins add additional requirements and getting a recent compiler versions on all operating systems might not always be trivial. Therfore it would be great to provide some docker images for building the ACTS software. The idea would be to provide one docker image with all supported compilers and dependencies for building ACTS with all plugins.

Ideally, the CI system should use these docker images itself for building and testing to ensure consistency. Optionally, upon creating a new tag, special docker images already containing the installed version of this specific ACTS tag could be provided.
