Is it possible to use docker as executor ?

**Is your feature request related to a problem? Please describe.**

When I configure some plugins on vscode, it's always not a easy thing.
It's amazing that runner only needs executor and then I get a idea sounds great.
Can we use a docker container as a executor?
It will pack the environment and is easy to run.
I am not familiar to vscode plugin developing. So I want to know is it possible ?

**Describe the solution you'd like**

In fact, the origin idea is set a debugging environment for C/C++ plugin.
It's convenient to organize package in java, python and go.
In C/C++, many libs are dynamic-link.
