EKS Cluster Source

[ribeiro-rodrigo]

The purpose of this task is to implement support for the origin of the EKS (Elastic Kubernetes Service) cluster.

Access information as a service account token will be passed on to the secret that the cluster source must know how to read.

The custom resource that contains the EKS source cluster should look like this:

  source:
    secretName: eks-secret
    eks:
      tags: {}
      ignore:
        - cluster1
        - cluster2
        - cluster3 

The rules for reading the secret performed by the cluster source must follow the requirements specified in issue #4
