Add "--expand" option for Certbot

[amotl]

Dear Jeff,

we want to salute you once more for one of your excellent contributions to the Ansible community in form of this recipe.

Because we want to aim at maximum DWIM by implementing our systems automation infrastructure with Ansible, we are in dire need of support for the --expand option of Certbot, using its webroot method. So, we picked up the contribution #117 by @ymarkus (thanks a stack!), wrapped it up and added corresponding support for webroot.

After that, expanding the list of certbot_certs.domains by another item and re-running the corresponding playbook immediately resolved the problem for us, where, beforehand, another subdomain was added to the list and the recipe was not able to pick up the change, without reporting back any kind of error.

We hope you will like the patch. I will add some comments to the PR, where I believe details about the implementation should be discussed. Thank you for taking the time to look into this!

With kind regards,
Andreas.

Do you believe the --expand option should be wrapped into another flag which determines its presence?

We are so used to using it all across the board, that we wouldn't even bother to omit it ;]. Do you see any negative impact on just having it as a default?

This might only work on Linux. macOS, by default, ships with corresponding non-GNU programs, where some of them have a different behavior. It will also not work natively on Windows.

So, I believe this spot should be improved?

Hi again. 9c0d000 improves the situation by removing any bashisms.
