Notes from testing hashiconf digital demo setup with Chris Piraino

Ran fake service in k8s, it has web/api/cache and db as subcomponents.

Ran k8s get pods to show the different components

Created first mesh gateways via systcl job

Spun up secondary dc, used k8s setup mechanism to get federation secret

Understanding system job reconcilation

Case	Current Behavior	Desired Behavior
New Job	Placed on all eligiblie nodes, queued allocs for nodes that don't have capacity
Node update
Job updated to have constraints
Job updated (any other update)
Node added with existing system jobs running on ineligible nodes
Node updated to match system job's constraint
