Chef::Knife::Ssh#configure_password

This is a bit overly complicated because of the way we want knife ssh to work with -P causing a password prompt for
the user, but we have to be conscious that this code gets included in knife bootstrap and knife * server create as
well.  We want to change the semantics so that the default is false and 'nil' means -P without an argument on the
command line.  But the other utilities expect nil to be the default and we can't prompt in that case. So we effectively
use ssh_password_ng to determine if we're coming from knife ssh or from the other utilities.  The other utilties can
also be patched to use ssh_password_ng easily as long they follow the convention that the default is false.
