Steps to Reproduce

The following playbook is expected to create a new vlan in the vlan_group: vlan_group1 with the next available vlan.

- name: "Test NetBox modules"
  connection: local
  hosts: localhost
  gather_facts: False

  tasks:
    - name: Create vlan within NetBox with only required information
      netbox_vlan:
        netbox_url: http://netbox.local
        netbox_token: thisIsMyToken
        data:
          name: Test VLAN
          vlan_group: vlan_group1
        state: present

However, this is not the case as the Netbox API will report:

    "msg": "{\"vid\":[\"This field is required.\"]}"

This is because the endpoint /ipam/ipam_vlan_groups_available_vlans_create should be used to alocate a vlan, when vid is not defined. It would be really nice with this feature in ansible.

Expected Behavior

A new vlan should be create with the next available vlan id from the vlan group.

Observed Behavior

Netbox API throws this error: "msg": "{"vid":["This field is required."]}" This is because the correct endpoint is not used to allocate a new vlan.
