Follow-up from !22: dealing with worhtless keys of cielito_hosts_users_data

The following discussion from !22 (merged) should be addressed:

• @apias started a discussion:

  If I define something like this:

  cielito_host_users_data:
    apias:
      choose_password: false
    ulvida:

  The role sets current_host_users_data like this

      "current_host_users_data": {
          "apias": {
              "authorized_keys": *************
              "choose_password": true,
              "name": "Andrés Pías"
          },
          "ulvida": null

  Resulting in users defined in OS like this:

  apias:x:1001:1004:Andrés Pías:/home/apias:/bin/bash
  ulvida:x:1002:1005::/home/ulvida:/bin/bash

  And the problem is in the line that originated this thread. Because, after combine, the worhtless keys of cielito_hosts_users_data overwrite the corresponding keys of cielito_user_data that have data.

  I will open a new issue for this.
