Introduce separate data channels for each local service instance element

[mariuswbr]

This PR introduces separate data channels (IPC connections via Proxy/Skeleton pattern, using mw::com) between the gatewayd and the someipd for each local service instance element. A local service instance is an offered service by an application running on the same ECU as the daemons. One of its elements would then be either an event or a method (or field as a composition of those).
Therefore instead of having one single Skeleton reference for all LocalServiceInstance objects for data transmission from gatewayd to someipd, there are now multiple Skeletons as part of the LocalServiceInstance class, one for each element.

The split into multiple data channels is done to ensure freedom from interference to a certain degree.
Furthermore scalability is another factor. Most of the SOME/IP messages will not need the full size of roughly ~1500 bytes.

The counterpart, the remote service instances shall be refactored in a similar fashion as soon as the GenericSkeleton is available from mw::com.

Resolves #8 partially.
