SSH is reloaded by default even if sshd_manage_service is set to false

[Ouack23]

Hello,

The documentation states that :

* `sshd_allow_reload`

If set to *false*, a reload of sshd wont happen on change. This can help with
troubleshooting. You'll need to manually reload sshd if you want to apply the
changed configuration. Defaults to the same value as `sshd_manage_service`.
(Except on AIX, where `sshd_manage_service` is default *false*, but
`sshd_allow_reload` is default *true*)

but the default variables set sshd_allow_reload to true : https://github.com/willshersystems/ansible-sshd/blob/master/defaults/main.yml#L14

So either the documentation is wrong and should be corrected, or the defaults file should be changed like this:

# If the below is false, don't reload the ssh daemon on change
- sshd_allow_reload: true
+ sshd_allow_reload: "{{ sshd_manage_service }}"

Thank you for reading :)

When this was introduced in bcd864f, the documentation was matching the code. But it is "broken" since 43ed7c1 which dropped the assignment.

I am worried that the problem with such assignment might have issues with the variable precedence (would have to double-check though). Do you want to open a PR with this change, ideally also with a reproducer tests to verify that it works as expected in the testing environment (probably only by checking variables as they are based on containers and do not have services running)?
