[PATCH v2 08/37] terraform/oci: Work around oracle/oci provider bug

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

First, I was getting

module.volumes[0].oci_core_volume.kdevops_volume_extra[0]: Creating...
╷
│ Error: 400-CannotParseRequest, Incorrectly formatted request. Please refer to our documentation for help.

No idea why, though maybe this is the first time I've tried using
us-east1 when my home region is us-central. Nothing I tried changed
this result, and there's no obvious problem with the way that the
oci_core_volume resource is specified, which hasn't changed in many
months.

All documentation I consulted stated that because the root module
explicitly specifies exactly one provider, child modules are
supposed to inherit that provider. But that isn't happening here:

$ terraform providers

Providers required by configuration:
.
├── provider[registry.terraform.io/oracle/oci] ~> 6.0
└── module.volumes
    └── provider[registry.terraform.io/hashicorp/oci]

And looks like it's a bug that was never fixed:
https://github.com/oracle/terraform-provider-oci/issues/1608

The only workaround I understood was to switch the root module
back to using the hashicorp/oci provider so that the root and
"volumes" module use the same provider.
