Move remaining SNAT code from VNC to SVC

Since this commit 4baf65c347ce13e34c500205f1d8c43b95d9da9
the SNAT code has moved from the VNC to SVC. however
there were some remaining code related to the route
table/interfaces association. This patch moves these
remaining codes.

This patch also introduces an agent manager
which handles and forward some evens during
the service instance creation. The goal
of this refactoring is to move the specific
pieces of code that are present in the
instance_manager closer to their related
agent.

Unit-tests have been added for the snat_agent.
