Allow override server.xml.j2 & setenv.sh.j2 template source

[Akivas]

Proposed feature

Allow the override of server.xml.j2 & setenv.sh.j2 template source in the instance.yml task file

Rationale

This would allow for template override if/when needed, to add or remove functionalities otherwise hardcoded in the template.

Additional context

I had to change the server.xml.j2 template to add new features like services, engines, hosts & aliases declaration but found myself stranded when I had to force the template task to use my own template (even using the same filename in my template folder)

Being able to set a template_src variable per instance would solve this problem :

tomcat_instances:
  - name: "{{ tomcat_name }}"
    server_xml_template_src : server.xml.j2
    setenv_template_src : setenv.sh.j2
    [...]

- name: instance | Configure tomcat instance - server.xml
  ansible.builtin.template:
    src: {{ instance.server_xml_template_src |default('server.xml.j2') }}
    dest: "{{ tomcat_directory }}/{{ instance.name }}/conf/server.xml"
    mode: "0644"
  notify:
    - Restart tomcat instance

This would be the same for the setenv.sh.j2 template.
