Add ability to register output of a task and make it available in templates context about task HOT 1 OPEN

register is also supported in Ansible. you use it not just for templates context, but for conditionals in the task itself using when: and probably others.

example from ansible docs

- hosts: web_servers

  tasks:

     - name: Run a shell command and register its output as a variable
       ansible.builtin.shell: /usr/bin/foo
       register: foo_result
       ignore_errors: true

     - name: Run a shell command using output of the previous task
       ansible.builtin.shell: /usr/bin/bar
       when: foo_result.rc == 5

The struct for vars created with register are kind of complex in a way which I'm not a huge fan of, but exit status (registered_var.rc) and stdout separate from stderr is very useful.

from task.
