Code available to VS Code and Deephaven Server do not match

[chipkent]

In remote development in VS Code or JetBrains, the code for the entire project is available in the container. The current plugin does not behave this way. Only the executed script is run on the server. This results in a very awkward workflow for code of any complexity.

Consider this simple example:

mymod.py:

print("IN MYMOD")

def myfunc(x):
    return x + 1

main.py:

import mymod

This results in:

ava.lang.RuntimeException: Error in Python interpreter:
Type: <class 'ModuleNotFoundError'>
Value: No module named 'mymod'
Line: 1
Namespace: <module>
File: <string>
Traceback (most recent call last):
  File "<string>", line -1, in <module>

As a result, python devs have no real way to create multi-file programs. One reason to move to VS Code is to allow more complex development. This does not work if multi-file programs are not supported.
