Support EKSA bundles

[gthao313]

Issue number:
https://github.com/orgs/bottlerocket-os/projects/26/views/7?pane=issue&itemId=58742846

Description of changes:
During release testing, we have high chance to meet the error on creating vmware or metal clusters. This is because The bundle.yaml used to create mgmt cluster is inconsistent with the bundle.yaml used to create test clusters. To solve this issue, we can download the bundle.yaml which uses to create mgmt-clusters and pass it as argument to eks-a binary. Therefore, when creating test clusters, it would be overrode to use the downloaded mgmt cluster bundle.yaml.

❌ Validation failed    {"validation": "validate eksa release components exist on management cluster", "error": "EKSARelease.v1alp
ha1.anywhere.eks.amazonaws.com \"eksa-v0-19-6-dev-plus-build-1\" not found", "remediation": "ensure eksaVersion is in the correct format (vMajor.Minor.Patch) and matches
one of the available releases on the management cluster: kubectl get eksareleases -n eksa-system --kubeconfig /local/eksa-work/mgmt.kubeconfig"}
