Add a conditional flag for windows and linux user_data

[ntwkninja]

looking to move a lot of the user_data things into ec2 image builder and create a conditional for the remaining specifics

The windows module capabilities is probably outside the scope of UDS (edge case). Need to validate this assumption and adjust the issue accordingly.

• If outside the scope of UDS, separate tf module will be created / maintained.

• If it falls within scope, we need to determine if we can reuse the module for both use cases or if we need to create a separate module.

  • Primary reason for this discussion is that the cloud_init functionality is linux-specific and windows strictly uses user_data

Is this still needed? I vaguely recall hearing that image builder stuff didn't pan out. Can this be closed?

[ntwkninja]

Still needed either way
