ALGO VPN running in an AWS Spot instance

Given the highlights from the Alestic blog Feb-2018, now enhance the Algo VPN Ansible script to start a spot instance vs on demand instance.

Alestic blog highlights reason to enhance algo script

Can run an instance like you normally do for on-demand instances. One new parameter can make it a Spot instance
Spot price volatility has been significantly reduced
No longer have to specify a bid price
CloudWatch Events can now send a two-minute warning before a Spot instance is interrupted
