Add workspace_key_prefix prefix to use an existing s3 tfstate bucket

[nitrocode]

Describe the Feature

I'd like to use an existing s3 bucket for tfstate for an atmos poc without cluttering up the s3 bucket's root space.

Preferably, i'd like to add a workspace_key_prefix of atmos/ before the component name

Expected Behavior

Everything is in root space

$ aws s3 ls s3://some-tfstate-bucket/
                           PRE ecr/           # from atmos
                           PRE hello-world/   # from atmos
                           PRE existing/
                           PRE # ...

Use Case

See above

Describe Ideal Solution

Add prefix for workspace prefix such as workspace_key_prefix_prefix or workspace_directory

Alternatives Considered

Create a new bucket

workspace_key_prefix can be specified per component, e.g.

  components:
    terraform:
      vpc:
        backend:
          s3:
            workspace_key_prefix: "my-vpc"

If not specified, then Atmos generates it automatically using the Atmos component name.
In the above case, if you don't use workspace_key_prefix: "my-vpc", then it will be set to vpc (Atmos component name).

And since the backend section participates in all the inheritance and deep-merging, you can specify workspace_key_prefix in any of the base abstract components, in a mixin, or any other config that would be applied to the component in question

@nitrocode is this what you are asking?

Hi @aknysh , it's similar. I want the workspace_key_prefix to be prefixed with another hard coded value which at the moment atmos does not support.

For example, a workspace_key_prefix equal to my <component> will give me this in my S3 bucket.

s3://tfstate-bucket/<component>

What I want is to prefix the workspace_key_prefix with a root level directory

s3://tfstate-bucket/<root-level-directory>/<component>

e.g.

  components:
    terraform:
      vpc:
        backend:
          s3:
            workspace_key_prefix: "vpc"
            workspace_key_prefix_prefix: "atmos/"

which should result in this

s3://tfstate-bucket/atmos/vpc

I don't want to do it on a per-component level (like in the example above) but on a global level where I define all my bucket information.
