[RFC PATCH 23/31] terraform/OCI: Remove TERRAFORM_OCI_VOLUMES_ENABLE_EXTRA

[cel@kernel.org]

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

Chandan and I have noticed that "enable extra disks, select 2 per
instance" is pretty much exactly the same as "don't enable extra
disks". Simplify the extra disks selector by removing the check
box and making "2 disks per instance" the default.
