User Story:

As a user of the HCP CLI, I want to be able to specify a NodePools arch from a flag so that I can easily create NodePools of different CPU architectures in AWS HostedClusters.

Acceptance Criteria:

• The HCP CLI contains a `arch` flag for the create cluster command for AWS.
• The HCP CLI contains a `arch` flag for the create nodepool command for AWS.
• The HCP CLI contains a `multi-arch` flag for the create cluster command for AWS.
• The only valid values for the arch flag are:
  • amd64
  • arm64

Out of Scope:

Other CPU arches are not being considered for the arch flag since they are unavailable in AWS.

Engineering Details:

• N/A
