This client exposes operations on generic metadata (get, list, watch, delete)
and allows patch operations. The client always uses protobuf and requests
the server transform the response into the appropriate object. Using this
client simplifies the work of generic controllers by allowing them to treat
all objects the same, and also improves performance both in the amount of
data sent as well as allowing protobuf on CRD resources.
Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

1. When the incoming patch specified a resourceVersion that failed as a precondition,
the patch handler would retry uselessly 5 times. This PR collapses onto GuaranteedUpdate,
which immediately stops retrying in that case.
2. When the incoming patch did not specify a resourceVersion, and persisting to etcd
contended with other etcd updates, the retry would try to detect patch conflicts with
deltas from the first 'current object' retrieved from etcd and fail with a conflict error
in that case. Given that the user did not provide any information about the starting version
they expected their patch to apply to, this does not make sense, and results in arbitrary
conflict errors, depending on when the patch was submitted relative to other changes made
to the resource. This PR changes the patch application to be performed on the object retrieved
from etcd identically on every attempt.
fixes#58017
SMP is no longer computed for CRD objects
fixes#42644
No special state is retained on the first attempt, so the patch handler correctly handles
the cached storage optimistically trying with a cached object first
