Add +support for the terraform support for Lambda Labs. The best provider docs are at +https://registry.terraform.io/providers/elct9620/lambdalabs/latest/docs . Then +To create the kconfig values you will implement support to use the lambda cloud +API to let us query for what type of instances they have available and so forth. +Therefore the Kconfig stuff for Lambda labs will all be dynamic. So we'll want +to expand this as part of what make dynconfig does. However note that dynconfig +does *all* dynamically generated kconfig.
