[New feature] Natively run Docker Containers build at runtime.

[laugimethods]

Right now, only scripted code or precompiled code (like Java in .jar files) can be run in Proactive (thanks to dedicated engines). Which dramatically limits the use of the tasks.

I suggest instead to allow the use of Docker Containers that can be build directly from the code defined in the tasks.

Please find attached a POC to demonstrate that approach : ScriptTask.java

However:

• the Docker build instruction should be provided as a parameter (defined in the studio)
• the docker image should be mutualized (and eventually destroyed to save space)
• use a real Docker repository so that the docker images could be distributed on multiple locations (servers)
• a dedicated DockerTask should probably be created
• instead of going with a generic bash script to call the docker command, a direct call might be implemented instead
• related to previous comment, a deployment through K8s should be considered
• in case of a larger code base than a simple script (which will be the norm if we consider Java code for example), a build from a (Git) repo should be an option
