Modular structure of clamp including controlloop

This commit is the first commit that puts in multi module structure while
changing the existing CLAMP code as little as possible.
It adds a structure where common, models, participant and runtime are direct children under clamp,
and current clamp code is moved under runtime. This runtime directory will host controlloop
runtime code in later commits.
