Refactor MSP package and msp config w/o json
This change-set presents a better organisation of the MSP package: code that belongs to msp proper is in fabric/msp, whereas core that instantiates and manages msps for the peer was moved in fabric/core/peer (a new package was created to avoid import cycles). Furthermore, configuration of the local MSP no longer requires a specific json file: it is sufficient to place certificates and keys in a directory with the appropriate structure (sample in msp/sampleconfig).
