I have to work with multiple Netbox instances.
It'd be nice to be able to use ENVs to specify netbox address and token.
Currently, to be able to work with 2 instances I had to run nbcli init twice with different NBCLI_DIR and now have to specify NBCLI_DIR env in order to make nbcli work with desired netbox instance.

Since I have no per-netbox preferences for filter results limits and search_objects - the configs differ only by pynetbox.url and pynetbox.token.
I think it'd be a bit better for such a case to have a common init dir (and user_config.yml) and be able to switch between netbox instances just by changing ENVs like NBCLI_URL and NBCLI_TOKEN.
