Create an own python interpreter

[Kiyotoko]

Is your feature request related to a problem? Please describe.
We currently have the problem, that python and related libraries need to be installed along with this java version. Therefore, a false, old or unchecked setup can easily lead to bugs and errors.

Describe the solution you'd like
This can be prevented by creating an own python interpreter that runs only in the Java VM and is system independent.

Describe alternatives you've considered
A alternative would be docker, which is to some degree already supported, or Jyphon, which only supports Python 2.7. Because seekers-py currently runs on 3.9 and above, this could only run with many fixes

Additional context
Python clients are currently launched over the ProcessBuilder API.

I strongly oppose Jython. It is kind of cursed and Python 2.x is long a thing of the past. I think that it should not be the Java server's responsibility to launch the python clients but a separate program's. Nevertheless, a docker image for the python client would be nice.
