[tacacs]: Add SSH TraceId authorization attribute support

[Rod-Persky]

This pull request introduces support for a new traceid_authorization option for TACACS+ authorization, allowing the system to include an SSH TraceId in TACACS+ authorization requests. The changes ensure this option is configurable, has a sensible default, and is properly reflected in configuration templates and tests.

New feature: TACACS+ TraceId Authorization

• Added support for the traceid_authorization option in TACACS+ configuration, defaulting to on, and updated the Jinja template (tacplus_nss.conf.j2) and sample output files to include this option and its documentation. [1] [2] [3]
• Introduced the TACPLUS_TRACEID_AUTHORIZATION_DEFAULT constant (default: True) and included it in the global TACACS+ defaults in hostcfgd. [1] [2]
• Ensured that the traceid_authorization value is correctly parsed and normalized when updating the global TACACS+ configuration.
• Updated the configuration rendering logic to pass the traceid_authorization value to the template.

Test updates

• Modified test vectors and sample outputs to cover the new traceid_authorization option, ensuring correct behavior when the option is set or unset. [1] [2]
