[PATCH 0/9] Adds support for launch-time parameter collection

This patch adds the ability to collect launch-time parameters and propagate those parameters to a config server. To do this, several pieces have been added: * add/manage config server connections per provider account * updated deployable_xml to know about "services" * UI elements added to collect launch-parameters (service parameters) during deployment launch * model elements added to capture launch parameters for later retrieval * UI added to display launch parameters post-launch
