Ability to manage maintenance in actions using Zabbix JS object/class

Hello

Could be related to ZBXNEXT-3644

With the idea to be able to manage maintenances "dynamically" from the agent side in an automated way, it would be great to be able to create and delete maintenance from the Zabbix Javascript internal object.

This would allow to manage maintenance from actions and media types.
A specific trapper item could trigger an action that would create or delete a maintenance.

For example, as we have "Zabbix.log" function, we could have Zabbix.Maintenance.[add|modify|delete] functions.

Another way would be to be able to call APIs from the javascript with a Zabbix.api (apiname, apidata) function. This would allow to use any already existing APIs.

Thanks,

Gaël
