Summary

Currently Zabbix UI forces users to switch from Monitoring to Configuration and back frequently in order to create new monitoring objects and check result.

Ability to create items from Monitoring section would greatly improve usability.

Use cases

1. I want to create new items from Monitoring→Latest data
2. I do not want to be transferred to another page when creating or updating an item

Аcceptance

1. Item configuration form must be made modal
2. New button "Create item" must be added to Monitoring→Latest data and new entry "Create item" must be added to host context menu
   1. If filtered by a single host, then the host must be pre-selected in the item definition form
3. The new buttons must be visible only if user has sufficient permissions
4. All existing links to configuration of items must lead to the new modal forms
