Currently if we disable cloud provider by the following
CLOUD_PROVIDER_FLAG=external
KUBE_FEATURE_GATES=DisableCloudProviders=true,DisableKubeletCloudCredentialProviders=true
we can no longer schedule workloads due to taints and a lack of
node configuration.
This pulls a CCM image from K/cloud-provider-gcp to run tests.
This is a pre-step for taking the above feature gates to beta.
It does not address the last known good dependency issue.
Specifically the CCM image is built on top of client-go and staging.
However this image will be an "old" verison of those libraries.
So it does not test if those libraries work in the CCM.
Fix shellcheck errors.
Add CCM_FEATURE_GATES for testing.
Switching to extended regex from perl regex.
Adding instrumentation to cluster configuration.
Improved regex to not greedily get key-value pairs.
Fixed issue with error on regex no line match.
Switch credentialprovider version to v1alpha1
