pause is only run on the first host and only that host get the variable
registered.
So the include task should have failed for db2 and db3 since they not have this
variable set unless you are reusing install_mysql.

Delegate_to does run the task on another host, but the variable is still
registered on the original host(the first host).
Pause doesn't support delegate_facts so you need to do this
- pause:
prompt: "Do you want to install mysql (yes/no)?"
register: install_mysql
- include_tasks: mysql.yml
when: hostvars[ansible_play_hosts | first].install_mysql.user_input | bool
