[ecpullen]

Issue number:
N/A

Description of changes:
Adds support for passing the EKS-A manifest release URL to the metal/vsphere cluster agents.

Waiting for next TestSys release to merge

Testing done:

With a dev configuration in Test.toml for 'quick' tests:

[vmware-k8s.configuration.quick.dev]
eks-a-release-manifest-url = "https://blah.cloudfront.net/baremetal/eksctl-anywhere-manifest.yaml"

Then kicking off vmware k8s tests:
