reload_config is called with non existing publisher argument

[TAlonglong]

Describe the bug

reload_config is called with a non existing publisher argument

reload_config is defined: https://github.com/pytroll/trollmoves/blob/main/trollmoves/client.py#L901 with only two arguments.

https://github.com/pytroll/trollmoves/blob/main/trollmoves/client.py#L1050-L1051 is called with a publisher argument not available.

A kill -HUP can trigger traceback like this:

move_it_client] reload_config() got an unexpected keyword argument 'publisher'
