    Add extension fwaas_v2 based on neutron-api relation data

    fwaas_v2 extension is added in l3_agent.ini by default from stein.
    However with the newly introduced neutron-api configuration parameter
    enable-fwaas, the extension have to added only when it is set to true
    on neutron-api charm.

    neutron-api charm adds enabled-fwaas as relation data in the commit
    https://review.opendev.org/c/openstack/charm-neutron-api/+/806676.
    This patch removes special handling of fwaas_v2 as l3_extension_plugins
    is already updated in relation data based on neutron-api enable-fwaas
    configuration.

    Remove python3-neutron-fwaas in package list from stein release. The
    package is already part of dependency of neutron-l3-agent until Ussuri
    release and the dependency will be removed from Victoria release in
    package control files.
