Imagine that during zabbix_server runtime there is a reason to change DB connection password, which is stored in a secure vault (HashiCorp, CyberArk).

When zabbix_server needs to recreate a DB connection, it still uses older password, cached when zabbix_server daemon has been started.

It would be nice if zabbix server reloads the password on some conditions, for example when DB authentication has failed (because password is different now).
