Move ipconnectivity.proto to services-proto.jar

Moved ipconnectivity.proto from services.core.jar to
framework-protos.jar.
Replaced 'mergeFrom' MessageNano base class calls, with 'parseFrom'
IpConnectivityLog calls.

This solves an issue where the services.jar would conflict with
duplicate nano proto base class definitions in other .jars
(wifi-service.jar).
