hardcoded region in fscloud examples + some misleading doc

[vburckhardt]

2 small issues:

1. Here:

   terraform-ibm-base-ocp-vpc/examples/fscloud/main.tf

   Line 241 in 03ee59e

   region = "us-south"

2. terraform-ibm-base-ocp-vpc/examples/fscloud/variables.tf

   Line 47 in 03ee59e

   description = "CRN of the Hyper Protect Crypto service to use to encrypt the cluster boot volume"

   and

   terraform-ibm-base-ocp-vpc/examples/fscloud/variables.tf

   Line 52 in 03ee59e

   description = "CRN of the Hyper Protect Crypto service to use to encrypt the worker pool boot volumes"

   documentation that this is the crn to the HPCS service, when it is the crn to keys in HPCS.
