[PATCH v3 05/36] terraform/azure: Make the resource group name a variable

[Chuck Lever <cel@kernel.org>]

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

Resource groups appear to be global. To run more than one instance
of kdevops in Azure at the same time, each instance needs a unique
resource group. Hoist the resource group name into Kconfig so that
it can be set to a unique value.
