This update was prompted by updates in openssh to the scp behavior
making source directory paths suffixed with `.` no longer valid
resulting in errors on upload. The upload implementation within
the ssh communicator has been updated to retain the existing
behavior.
Included in this update is modifications to the winrm communicator
so the upload functionality matches that of the ssh communicator
respecting the trailing `.` behavior on source paths. With the
communicators updated to properly handle the paths, the file
provisioner was also updated to simply apply previously defined
path update rules only.
Fixes#10675
As of `net-ssh` version 4.2.0, the key :paranoid has been deprecated in
favor of using :verify_host_key. This commit updates Vagrants ssh config
to use the new key, and deprecates the use of :paranoid.
