Cannot set multiple IP ranges on an IP Pool

[dandunckelman]

Summary

When creating/updating a nsx_ippool, I'd like to be able to pass a list of IP ranges.

Currently, the module allows for only one range in a pool.

Possible interface

tasks:
  - name: ip pool with multiple ip ranges
    nsx_ippool:
      ip_ranges:
        - start_ip: '10.1.10.1'
          end_ip: '10.1.10.10'
        - start_ip: '10.1.10.11'
          end_ip: '10.1.10.20'
      end_ip: '{{ ESX_IP }}'
      gateway: '10.1.10.1'
      name: 'test'
      nsxmanager_spec: "{{ nsxmanager_spec }}"
      prefix_length: '24'
      state: present
