Fix for int port assignment in a playbook failing

Ports are integer values but the old code was assuming they were
strings.  When login_port is put into playbook complex_args as an
integer the code would fail.  This update should make the argument
validating make sure we have an integer and then we can send that value
directly to the relevant APIs.

Fixes #818
