Zabbix 5.0.x does not support password policy and user can set weak password.

I know zabbix 6.0 has added password policy function. However in my situation, upgrade from 5.0 to 6.0 is impossible , as we use zabbix proxy for different server clusters ownered by different group and they won't upgrade zabbix proxy.

Please add the  password policy function to zabbix 5.0.x.
