Ports the bats unit, chart-verifier, and bats acceptance tests to use
github workflows and actions. The acceptance tests run using kind, and
run for multiple k8s versions, on pushes to the main branch.
Adds a SKIP_CSI env check in the CSI acceptance test, set in the
workflow if K8s version is less than 1.16.
Adds kubeAdmConfigPatches to the kind config to allow testing the CSI
provider on K8s versions prior to 1.21.
Updates the Secrets Store CSI driver to 1.0.0 in tests.
Makes the HA Vault tests more robust by waiting for all consul client
pods to be Ready, and waits with a timeout for Vault to start
responding as sealed (since the tests on GitHub runners were often
failing at that point).
