[WIP] Remove option to allow any top level parameter

[jaywcarman]

Some modules do not support any top level parameters, which is also
represented as an empty list (causing unsupported arguments like
'ibmcloud_api_key' to be templated into the Terraform block). There
aren't any modules that allow arbitrary parameters so this option is not
even needed.

fixes #61

I'm testing with this PR and it does fix the problem with ibm_is_images_info but I think it breaks a list of dicts for example https://github.com/IBM-Cloud/ansible-collection-ibm/blob/master/examples/simple-vm-ssh/create.yml#L70-L71, this renders primary_network_interface with no subnet:

resource ibm_is_instance "ansibletestvsi" {
  name = "ansible-test-vsi"
  vpc = "r006-20df8e8d-4ef4-4311-8122-7929db1232c8"
  profile = "bx2-2x8"
  image = "r006-988caa8b-7786-49c9-aea6-9553af2b1969"
  keys = ["r006-75132256-1f0e-437b-b973-366bdd2d02a5"]
  primary_network_interface {
    }
  zone = "us-south-3"
}

Edit: it's also dropping port_min and port_max here for example: https://github.com/IBM-Cloud/ansible-collection-ibm/blob/master/examples/simple-vm-ssh/create.yml#L104-L105

@jaywcarman , can you please attach test results for this?

@kavya498 I'll need to make updates before this can be merged, but am not sure when I'll have time. Moving this to a WIP for now.
