e1853a7d5b
Adds a new svc-map element which can be used to install services based on an in element 'svc-map' YAML config file format. This change is intended to decouple elements from DIB and allow new elements to support multiple distributions (with various service naming schemes) without having to constantly maintain DIB's various bin/map-services files. This patch ensures all of the YAML files are compiled into a single file without namespaces. The YAML compilation process occurs during image creation time and errors if conflicting mappings are found. Change-Id: Id11433ea342aace71a358936a7ca3151ec11d506
