User story:

So that I can safely upgrade an HCP machine pool, as a user, I want to use an upgrade policy.

NOTE: This is a minimally user-impacting change that changes the endpoint on how an HCP machine pool is updated including using the new node pool upgrade policy API endpoints.

Acceptance criteria:

• An option to upgrade an HCP machine pool will be shown if:
  • The control plane is not currently being updated
  • The machine pool version is behind the control plane
  • The machine pool does not have an automatic upgrade policy
  • The machine pool does not have a scheduled update.
• If an option to upgrade an HCP machine pool is available, the only option is to upgrade "now" (aka in the next hour) to the version as the control plane
• If at least one machine pool can be updated then there is an option to update all machine pools (current functionality - but instead an upgrade policy will be created for each machine pool)
• If there was an error upgrading a machine pool, an error will be displayed with an option to upgrade again
• If a machine pool is scheduled to be updated, then a message will be shown for that machine pool in the machine pool list
• There is a message informing users that if they need to schedule an upgrade or upgrade to a particular version they can use the CLI
