Ability to deploy a Cluster topology

[larslilja]

Problem Statement

Today the standard topology only includes 1 Manager instance. But we see more and more requests for Cluster tests, and hence an ask to be able to easily stand up an topology with a 3 node cluster.

Please describe the problem to be addressed by the proposed feature.

Proposed Solution

Lets either add a flag to deploy a default topology with 3 node cluster and 1 vbond 1 controller.

Or add an entire new "deploy_cluster" task in the tool that deploys that cluster topology.

Please describe what you envision the solution to this problem would look like.

Alternatives Considered

An alternative could be to create a flag for the "deploy" task that will allow us to deploy various topologies in the future.
Something like

Deploy --topology

and then we can over time expand the topology types, it could MRF toplogies, SD-Routing Topologies with DM-VPN or Flex. Or simila use cases.

Please briefly describe which alternatives, if any, have been considered, including merits of alternate approaches and
tradeoffs being made.
