gbproxy: Remove array of three cell IDs 

The hard-coded array of three cell identifiers in the ConnHdlr
configuration doesn't really reflect situations with a different
number of PCUs than three, and a different count of BVCs than one
per NSE.

Let's pass the entire PCU configuration as parameter into every
ConnHdlr.  This way, the ConnHdlr can learn whatever cell identities
there mgiht be in whatever number of BVCs of each NSE.
