create-servers-bare-metal.yml

### notes: if deploying to a new DC with no network, it fails. Perhaps add checking for this and deploying new network?
### create a way to delete cluster?

### usage:
# must have passwords.yml file with 'server_password', 'server_count' and 'public_key' variables defined
#
# ansible-playbook name-of-this-file.yml --extra-vars "server_group=ca2-k8-dev-5 location=ca2 server_count=2 password_file=/root/passwords.yml" 
#
### note: now need to also pass cpu_size and mem_size
