SIP-8: Devops - New validator region

In AWS speak a region or AZ is an availability zone. This denotes where in the world and in which AWS server farm the validator will live.

We currently run 170 validators on a C5.2xlarge in the us-east-2 AZ. This is Ohio.

Pros:

• Adding a new AZ reduces the chances of the validator going down if the server has an outage.
• This makes our infrastructure more "decentralized" in the sense that the servers are more geo-differentiated

Cons:

• Additionally cost and devops overhead from running a second server in a different region with its own VPC, subnet etc.
