This moves to a more generic config parser that doesn't have plugins parsing part of the tree. I understand why it ended up that way; we have "partitions" key which has special semantics compared to others keys and there was a desire to keep it isolated from core tree->graph code. But this isn't really isolated; you have to reverse-engineer several module-crossing boundaries, extras classes and repetitive recursive functions. Ultimately, plugins should have access to the node graph, but not participate in configuration parsing. This way we ensure that plugins can't invent new methods of configuration parsing. Note: unit tests produce the same tree -> graph conversion as the old method. i.e. this is not intended to have a functional change. Change-Id: I8a5d62a076a5a50597f2f1df3a8615afba6dadb2
