fix: msk_cluster cannot concurrently support multiple client auth strategies

[bpleines]

Summary

When using the msk_cluster module, I noticed that even when I specify multiple authentication strategies, only unauthenticated is picked up.

- name: Provision msk cluster
  msk_cluster:
    name: bpleines_msk_cluster
    state: present
    version: 2.4.1.1
    nodes: 3
    authentication:
      sasl_iam: true
      sasl_scram: true
      unauthenticated: true
...

Upon further inspection of the source code, I noticed that it is due to this code section. Current logic specifies that if unauthenticated set to true, the entire parent c_params["ClientAuthentication"] dictionary gets overwritten.

By altering the relevant code section to the following, I was able to test that the module brought up an msk cluster with all 3 authentication methods as desired:

        if module.params["authentication"].get("unauthenticated"):
            c_params["ClientAuthentication"]["Unauthenticated"] = {"Enabled": True}

I'd be happy to open a PR if allowed 😄
