paloalto_panos_brace_to_set does not handle banner correctly

[cheenpo]

Environment

• Python version:
• netutils version:

Expected Behavior

The banner configuration is not being included in paloalto_panos_brace_to_set

Observed Behavior

The banner configuration is not included.
This is a multi-line PAN-OS banner definition:

deviceconfig {
        system {
          login-banner "####################################################
WARNING TO UNAUTHORIZED USERS:
This system is for use by authorized users only.

acknowledges and consents to the right of the

this system. Unauthorized and/or improper use of
this system, as delineated by corporate policies,
is not tolerated and the company may take formal
action against such individuals.
####################################################
";
}
}

I believe the main issue is that the function checks whether a line ends with login-banner ", which is not the case for multi-line PAN-OS banner.

Steps to Reproduce

1. set the above to a string_of_config
2. try the following command show_config_merged_set_format = paloalto_panos_brace_to_set(string_of_config, cfg_type="string")
