#This script basically creates a VM (based on below specs) and joins that node to swarm as worker.
#It also labels the node as specified 

#This should take a few arguments 
#1. VM name
#2. SAVI Username 
#3. SAVI Password 
#4. Label_key (can be 'role' or 'loc')
#5. Label_value (can be 'monitor' or one of the following: 'core', 'edge', 'agg-sensor'
