Step to manually create nutanix cloud-controller-manager credentials and configs seems redundant and somewhat confusing

4.13/4.14 of openshift-install/ccoctl components 

Very 

Starting in this section of document: https://docs.openshift.com/container-platform/4.13/installing/installing_nutanix/installing-nutanix-installer-provisioned.html#manually-create-iam-nutanix_installing-nutanix-installer-provisioned    

1. After you create nutanix pc credentials yaml file and run through procedures to do `oc adm release extract` (example below) of

`oc adm release extract --credentials-requests --cloud=nutanix --to=credrequests -a pull-secret.json $RELEASE_IMAGE`

the output of that directory is actually:

```
0000_26_cloud-controller-manager-operator_18_credentialsrequest-nutanix.yaml
0000_30_machine-api-operator_00_credentials-request.yaml
```

vs. what is documented in 4.13+ scenarios in step 3 (which seems to be output of versions prior:

`0000_30_machine-api-operator_00_credentials-request.yaml`

2. In the following step, when you run `ccoctl nutanix create-shared-secrets`
the manifests folder seems to be created with the following files:

```
Saved credentials configuration to: manifests/openshift-cloud-controller-manager-nutanix-credentials-credentials.yaml

Saved credentials configuration to: manifests/openshift-machine-api-nutanix-credentials-credentials.yaml
```

3. After running `openshift-install create manifests` step and copying in the credentials files as directed, the final output actually looks like the following:

```$ ll manifests/
total 72
-rw-r-----. 1 nutanix nutanix 580 Dec 3 19:15 cloud-provider-config.yaml

-rw-------. 1 nutanix nutanix 287 Dec 3 19:15 openshift-machine-api-nutanix-credentials-credentials.yaml```

vs what is actually documented in output of step 7:

```
-rw-r----- 1 <user> <user> 2335 Jul 8 12:22 cluster-config.yaml
-rw-r----- 1 <user> <user> 161 Jul 8 12:22 cluster-dns-02-config.yml

-rw-r----- 1 <user> <user> 171 Jul 8 12:22 cluster-scheduler-02-config.yml
-rw-r----- 1 <user> <user> 200 Jul 8 12:22 cvo-overrides.yaml

-rw-r----- 1 <user> <user> 1304 Jul 8 12:22 kube-system-configmap-root-ca.yaml
-rw-r----- 1 <user> <user> 4090 Jul 8 12:22 machine-config-server-tls-secret.yaml
-rw-r----- 1 <user> <user> 3961 Jul 8 12:22 openshift-config-secret-pull-secret.yaml
-rw------- 1 <user> <user> 283 Jul 8 12:24 openshift-machine-api-nutanix-credentials-credentials.yaml
```

The difference between the two directory structures being that the `cloud-provider-config.yaml` and `openshift-cloud-controller-manager-nutanix-credentials-credentials.yaml` already exists.

The confusion is that the section right after this one states that the user needs to manually create and modify both of those same files respectively even though they already exists manually before running `openshift cluster install step`.

Steps documented in this section seemed to not be required https://docs.openshift.com/container-platform/4.13/installing/installing_nutanix/installing-nutanix-installer-provisioned.html#nutanix-ccm-config_installing-nutanix-installer-provisioned 

 This is also documented in 4.14
