This commit also introduces a dochelper concept. This provides some convenience methods to the document pkg that help extract data from known document types as well as walk document relationships to discover related information such as BMC credentials for baremetal hosts. Once merged, a follow up patchset will leverage these within the cloud-init code to deduplicate some of these lookups. Change-Id: Ie6a770ce4b34adbea30281917f0cb2fdc460b4fb
