Fixes #12147

moved WinRM setup script test after config

Rebase of 10204 - Add host key for ssh url only.

Rewrite function `get_fqdn`.  It returns fqdn for all kinds of urls now.

`add_git_host_key` determines whether a url is ssh and whether its host
key should be added.

Fixes #12099

FieldAttributes will now by default not be post_validated unless a flag
is set on them in the class, as a large number of fields are really there
simply to be inherited by Task/PlayContext and shouldn't be templated too
early.

The other (unrelated to the base issue) in #12084 is also fixed here, where
the roles field is loaded before vars/vars_files, meaning there are no vars
yet loaded in the play when the templating occurs.

Fixes #12084
