Add SoftwareConfigTransport for switching transports

This change adds a SoftwareConfigTransport parameter to role templates
so that the transport can be changed via a parameter_defaults entry.

This change will have no effect on an existing overcloud as the current
default POLL_SERVER_CFN is now explicit in the parameter default.
