Code Issues Proposed changes

Fix build-nodes-json for routed networks 

When using routed networks, i.e multiple provision networks
passing in the evironment file to build-nodes-json did'nt work.
It resulted in key errors when looking up the mac address of the
provision_net interface.

This change automates this by creating a provision_net_map, mapping
baremetal_port id's to subnet names.

Also deprecates the --provision-net option as it is no longer needed.
