This is to avoid unnecessary GCE API calls done by getInstanceByName
helper, which is iterating over all zones to find in which zone the
VM exists.
ProviderID already contains all the information - it's in the form:
gce://<VM URL> (VM URL contains project, zone, VM name).
ProviderID is propagated by Kubelet on node registration and in case
of bugs backfilled by node-controller.
'docker pull' is a time consuming operation. It makes sense to check
if image exists locally before pulling it from a registry.
Checked if image exists by running 'docker inspect'. Only pull if
image doesn't exist.
- add ./hack/tools/go.mod, this makes ./hack/tools a distinct module
- hack/tools/tools.go undescore imports bazel related tools, over time we
can add others.
- hack/*.sh scripts will cd to hack/tools and go install tools from there

During a parallel test run these tests were observed to cause a
preemption of another test:

These tests have no need to actually land on a node to validate resource quota and so we can set an impossible scheduling condition. Hopefully we don't have tests that too broadly check impossible scheduling conditions.
The admission cache may take longer to see both ingress classes
than it takes to create the ingress. We must loop until we see
the appropriate error, cleaning up after ourselves as we go.
Don't set a connection deadline for reading, because the read operation will
fail if no data is reaceived after the deadline, and will not keep the
connection in the close_wait status.
Logs at lower verbosity to match other generators
Switches major/minor return types to int
Prefixes generated method names with APILifecycle to avoid collisions
Adds a k8s:prerelease-lifecycle-gen:replacement=group,version,kind tag for indicating a replacement API
