[BUG] The duplicated backend config does not generate a new server id.

[lebeier]

I believe this is suppose to be a bug. When I duplicate the backend config via the pfsense ui, the id for the server is non-unique. This causes redirection loops.

backend pve_backend_ipvANY
        mode                    http
        id                      102
        log                     global
        timeout connect         30000
        timeout server          30000
        retries                 3
        load-server-state-from-file     global
        server                  pve 10.0.0.2:8006 id 101 ssl check inter 1000  verify none resolvers globalresolvers

backend pfsense_backend_ipvANY
        mode                    http
        id                      100
        log                     global
        timeout connect         30000
        timeout server          30000
        retries                 3
        load-server-state-from-file     global
        server                  pfsense 10.0.0.1:8443 id 101 ssl check inter 1000  verify none resolvers globalresolvers
