Split Shim-layer architecture and Integrated architecture
Create two sub-sections in "05 Detailed architecture" for the Shim-layer architecture and the Integrated architecture. Fix several implementations bugs and warnings. Remove numbering of files. JIRA: PROMISE-57 Change-Id: Ia0b4067c0cc3a461e54b6b010f8310764fb08d73
