[feature] Allow custom commands to reuse code from other ones

[danimtb]

What is your suggestion?

When developing custom commands, it is very likely that you would have to repeat some code and share it with other commands.

To do show, it will be nice to alllow importing code from other files (other custom commands) as python modules. This is not possible currently, as you can see here: conan-io/conan-extensions#45

So, as example, the expected feature would be:

cmd_build_info.py

...
from cmd_server import read_servers


@conan_subcommand()
def property_set(conan_api: ConanAPI, parser, subparser, *args):
    """
    Set properties for artifacts under a Conan reference recursively.
    """
    servers = read_servers()
    ....
