User story:

So that I don't accidentally try to add more than the maximum number of nodes (51) across an HCP cluster, as a user, I want the UI to not give options that would cause the cluster to go over the maximum number of nodes when adding a new machine pool.

Acceptance criteria:

• When adding a HCP machine pool (aka node pool):
  • For non-autoscaling, the drop-down options do not let me go over 51 total nodes.  For example: if the cluster has three nodes: mp-A has 3 nodes, mp-B has 2 nodes, and mp-C has 10 nodes.  If I edit mp-C, the largest option would be 46 nodes.
  • For autoscaling, I cannot push the + button on the max nodes to go over 51 total nodes. 
  • For autoscaling, if I enter a value in the max nodes that would go over 51 total nodes, an error is shown

Mockups:

No design changes, just a limit on the max number of nodes to 51
