Pass node-specific data into config-handler script

[phil-dileo]

This RFE is designed to provide the script with some node-specific information that might assist users craft their config-handlers. Right now we call the config-handler script like:

proc = subprocess.Popen(script, stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True)

The proposal is to create a dictionary with some other useful information that gets passed into the child process.

env_info = { 'NODE_IP': request.remote_addr, 'NODE_ID': node_id, 'CONFIG_PATH': filename } 

subprocess.Popen(script, stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True, env=env_info)

These variables are already present in the function and would require no extra digging.
