Create persistent custom commands #908

I would like to use my own debug commands in the VSCode Debug Console. PDB has the option to create aliases and store them in ~/.pdbrc for all debug sessions. Does debugpy have anything like this? If not, could it be added?

For a concrete example of something I am trying to do: I would like a function foo to be available in all my debug sessions that does the following:

def foo(o): # shows all non-internal methods for an object
    for m in dir(o):
        if m[0] != '_':
            print(m)

I can define this function in the console itself but I would like to place it (and possibly many others) in a debugger configuration file somewhere.
