Currently puppet-swift provides default values for some password
parameters, but this is not ideal from security perspective and we
should expect operators to set their own password explicitly.
This patch deprecates the usage of these default values and adds
warning message which appears for missing password defined, so that
we can remove current default values in next cycle.
