[ansible-project] Variable list depending on groups

[p***@prism-dm.co.uk]

I am using the zabbix_hosts module.

Depending on the groups that a particular host is in, I need to link to
various Zabbix templates.

So:
if a server is in dbservers I need to link it to "Template App MySQL"
if a server is in webservers I need to link it to "Template App HTTP
Service"

If a server is in both groups, it needs to be linked to both the above
templates.
Additionally all the servers need to be linked to "Template OS Linux"

So in the module group, the "setting link_templates:" will end up needing
to be fed values such as:


link_templates:
- Template OS Linux
- Template App MySQL


link_templates:
- Template OS Linux
- Template App HTTP Service

link_templates:
- Template OS Linux
- Template App HTTP Service
- Template App MySQL

Of course, this is only a small subset of the possible groups/templates.

Can someone suggest a neat way to build up the list so that I can code the
task as something like:

- name: Create a new host or update an existing host's info
local_action:
module: zabbix_host
server_url: http://zabbix.server/
login_user: ansible
login_password: ansible_password
host_name: "{{ inventory_hostname }}"
host_groups:
- Linux servers
link_templates: "{{ templates_list }}"
status: enabled
state: present
interfaces:

TIA
