Make SSH banner path configurable

[liteua]

Is your feature request related to a problem? Please describe.
Some security implementation guides require warning banners to be consistent across the system:

• CCE-27314-4

• V-72225

So, when running openscap audit of the server where sshd is hardened by this role, rule "Enable SSH Warning Banner" fails, as it expects ssh banner path to be '/etc/issue'.

Describe the solution you'd like
It would be nice instead of having '/etc/ssh/banner.txt' hard-coded in the opensshd.conf.j2 template:

Banner {{ '/etc/ssh/banner.txt' if (ssh_banner|bool) else 'none' }}

have a variable like ssh_banner_path for this:

Banner {{ ssh_banner_path if (ssh_banner|bool) else 'none' }}

ssh_banner_path variable default could be set to current path '/etc/ssh/banner.txt'.

This sounds reasonable. Do you want to create a PR for that?

[liteua]

Yes, sure ) Already done.
