Dockerfile Parts (#428)

* De-duplicate Dockerfiles by using a bash file to concatenate common parts

Resolves #375.

Dockerfiles are still committed to the repo to avoid a dependency on bash.

* Add a CI job to confirm the committed dockerfiles are the currently generated ones

* Create dedicated Dockerfiles per processor network

Ensures the compromising of network-specific dependencies doesn't lead to a
compromise of the build process for all processors.

* Dockerfile corrections

* Correct call to build processor Docker image in tests/processor
