As a developer of NextGen Edge, I need:

• To update etcd configuration to allow for 2 learners.
• The scaling command utility to prompt the user for new node information.
• The scaling utility to copy over the necessary authentication config to the new nodes after being given two node IPs.
• Updated startup logic to allow new nodes to join an existing cluster as learner instances.
• The command line utility on the original node to confirm the new nodes are ready for promotion.
• The scaling utility to promote both new nodes together and report a successful scale-up operation.

Acceptance Criteria:

• A recorded demo of the scale-up operation is created.
• PRs are filed into the microshift repository to handle the new scaling logic.
