[aplathrop]

SUMMARY

Adds the ability to rename objects in Zabbix

ISSUE TYPE

• Feature Pull Request

COMPONENT NAME

• zabbix_item
• zabbix_trigger
• zabbix_discoveryrule
• zabbix_itemprototype
• zabbix_triggerprototype

ADDITIONAL INFORMATION

Currently the only way to rename resources using the Ansible modules is to delete the resource under the old name and recreate it under the new name, despite that the Zabbix API supports renaming these types of resources.
The UID for these resources from the API's point of view is a number, not the name. As that's not very user friendly, when I wrote the modules, I use the resource name and the host/template name to lookup the ID. Unfortunately, the side effect of this is if you try to rename a resource, the module will try to create a duplicate resource with the new name
I've been using the above work around of deleting and recreating, but that has its own unfortunate side-effect that you lose the historical data
This PR adds a new_name parameter like below:

- name: Rename Zabbix item
  community.zabbix.zabbix_item:
    name: agent_ping
    template_name: example_template
    params:
      new_name: new_agent_ping
    state: present

In this example, the module lookup the itemid for a Zabbix item with the name agent_ping in the template example_template. It will then set the name field for the item with the id to new_agent_ping
