Hi Zabbix devs,

Since Zabbix agent 2 added custom SQL queries, we can add .sql files to our servers to execute SQL queries. It would be a lot easier to manage the queries however if we could do it directly from frontend.

As such, I'd like for Zabbix to move from .sql files to direct from frontend SQL queries on agent 2 DB plugins. More like the current ODBC monitoring query field. 

Easier to manage and the security is still handled by our DB user.
