Add Support for AWS Resource EKS

[jmurillo9]

Description
After reviewing the documentation referenced here, it appears like AWS EKS is not currently supported. It would be amazing to support this AWS service so that we can get some drift detection on these resources.

Example
Ideal scenario, I can setup a .driftignore file that looks like this:

*
!aws_eks_cluster*

Then when I run driftctl, I can either query my statefiles in S3 or pull them down locally to compare and see the diff.

Thanks again in advance for considering this.
