Rajiv Kumar 10e85ee6ce Consolidate heat network resources 
Currently for each driver has following code
  1) Create a fixed Network.
  2) Create a fixed subnet in the network created at step 1.
  3) Create a router
  4) Attach subnet(created at step2) to router(created at step 3)

A new resource is created for above tasks in network.yaml file.
New resource does the above tasks and output the fixed network ID
and fixed subnet id, which is used by other parts of the heat
template.
