[Bug] recovery_plan fails to create in module plugin_modules/prism/recovery_plans.py

[stahnjones]

Describe the bug
a valid recovery plan configuration specification does not create due to API requiring "kind": "cluster" when referring to a cluster's UUID

To Reproduce
Steps to reproduce the behavior:

1. ansible command: ansible-playbook create-test-recovery-plan.yml
2. sample playbook used

- hosts: localhost
  gather_facts: false

  tasks:
    - name: create test recovery plan
      ntnx_recovery_plans:
        nutanix_host: "<pcip>"
        nutanix_username: "<pc-username>"
        nutanix_password: "<pc-password>"
        validate_certs: false
        state: "present"
        name: example-rp
        desc: recovery plan desc
        stages:
          - vms:
              - name: "test-check"
            delay: 0
        primary_location:
          url: "<pc_uuid>"
          cluster: "<source_pe_uuid>"
        recovery_location:
          url: "<pc_uuid>"
          cluster: "<dest_pe_uuid>"
        network_type: NON_STRETCH
        network_mappings:
          - primary:
              test:
                name: "<subnet-name>"
              prod:
                name: "<subnet-name>"
            recovery:
              test:
                name: "<subnet-name>"
              prod:
                name: "<subnet-name>"
      register: result

Expected behavior
a recovery plan is created with the specification provided

Additional context
fails to create with a vague error about being unprocessable entity. When using check_mode, take the resultant API request body into the Prism Central API directly and returns a more specific error about the lack of kind: cluster
adding in "kind": "cluster" to the resultant request json allows the RP to be created as desired
