Description of problem:

In OSD AWS CCS (also in Non-CCS) wizard flow, There was a wrong mention on "Authentication type" as service account in "Review and create" step. This is wrong as there no service account definition /options associated to AWS wizard flow. We would need to remove authentication type definition from there.

Additionally user has no option to configure authentication type from GCP Non-CCS wizard flow. But the Review and create step shows "Authentication type" as service account. Probably it would be good to remove that option from Non-CCS flow as user doesn't configure explicitly.

How reproducible:
always

Steps to Reproduce:

1. Open OCM UI staging 
2. Open OSD wizard.
3. In billing model, Select "Subscription type" as "Annual fixed capacity subscription from Red Hat" and select "Infrastructure type" as "customer cloud subscription".
4. Click "Next" button.
5. Select Cloud provider as "AWS".
6. Proceed to next steps with all required values filled.
7. Reach to "Review and create" page .
8. See the "Authentication type" definitions
   Note: repeat the same steps with "Infrastructure type" as "Red Hat cloud account" as well as with both AWS and GCP cloud providers.

Actual results:

"Authentication type" wrongly tagged in "Review and create" page with value as "Service account" for AWS CCS OSD flow as well as AWS/GCP nonCCS OSD flow.

Expected results:

Remove "Authentication type" referenced from both AWS CCS OSD  as well as "AWS/GCP nonCCS OSD" wizard flows
