HCP Waypoint agent actions support

[HenryEstberg]

🛠️ Description

Added new supported action type to the hcp_waypoint_action resource and data source. In addition, added new hcp_waypoint_agent_group resource and data source.

As a note to reviewers, adding new test cases in the action resource and data source appears to have either caused a race condition, or made it far more likely. This appears to have been solved by making those tests in particular not parallelized like the rest of the Waypoint acceptance tests. I have not been able to reproduce the failure after making that change.

PCI review checklist

• If applicable, I've documented a plan to revert these changes if they require more than reverting the pull request.

• If applicable, I've worked with GRC to document the impact of any changes to security controls.

  Examples of changes to controls include access controls, encryption, logging, etc.

• If applicable, I've worked with GRC to ensure compliance due to a significant change to the in-scope PCI environment.

  Examples include changes to operating systems, ports, protocols, services, cryptography-related components, PII processing code, etc.
