issue occurs when using arg "-p" in python code

[markict]

when I use Connection from unicon, and the args list contains -p the issue will occur.

we can reproduce this issue by the following code and cmd:

python3.10 hello.py -p ~/Downloads/magpies.rar

hello.py

from unicon import Connection

login_info = {
    # the login info items
}

if __name__ == "__main__":
    # let's suppose the arg "-p" is for other lines (not for pyats)
    # xxxx

    con = Connection(**login_info)

seems pyats treats the arg -p as its config file, however, intercepting the args should not be our expectation, yes?

You can achieve something similar like this: https://pubhub.devnetcloud.com/media/pyats/docs/topology/example.html#example-testbed-file with the custom parameter.
