Make universal dockerfile

In repository, we have .devcontainer folder with environments for different combinations Python and cpptango versions. However, the set is limited and does not include the environment for cpptangodev.

I purpose to create a universal Dockerfile, where user sets Python and cpptango versions as build arguments, and it automatically makes the environment.

Also in case user wants to try latest cpptangodev, the latest TangoTest device will be automatically compilied
