1. Proposed title of this feature request

Allow Compact cluster with any number of workers to be valid in Assisted Installer for Day1 installation

2. What is the nature and description of the request?

Currently, Assisted Installer doesn’t allow a topology which consists of a compact cluster with any number of workers, with or without ODF, to be provisioned in Day1.

As an example, while trying a compact cluster with 1 or 2 additional worker nodes, the Install button is disabled and a warning message appears on the UI, informing that it is required to have at least 3 worker nodes. On the contrary, a compact cluster (w/ or w/o ODF) without any additional worker nodes is a valid topology for AI.

The request is to allow a topology of compact cluster (4.9 and up) and any number of additional worker, with or without ODF, to be valid in Assisted Installer in Day1.

3. Why does the customer need this? (List the business requirements here)

It is feasible to add any number of worker nodes after the initial installation of a compact cluster using Day2 operations, however this adds a significant amount of time and complexity in the overall Day1 provisioning process of the desired cluster.
