[FAB-2336] Add application/MSP to genesis.yaml

https://jira.hyperledger.org/browse/FAB-2336

The genesis.yaml file currently only contains the bootstrapping
parameters necessary for the orderer (without MSPs).  This CR adds the
additional configuration variables needed for MSPs and the application
side, and populates them into config structures.  No one consumes them
yet however.
