This change updates the transport.Config .Dial and .TLS.GetCert fields
to use a struct wrapper. This indirection via a pointer allows the
functions to be compared and thus makes them valid to use as map keys.
This change is then leveraged by the existing global exec auth and TLS
config caches to return the same authenticator and TLS config even when
distinct but identical rest configs were used to create distinct
clientsets.

Having to list all packages isn't very manageable and requires constant
maintenance that is easy to miss. For example, test/e2e/framework/daemonset was
created without adding an entry for it. Promptly one file doesn't use the
intended e2edaemonset alias.
A simpler solution is to support matching the import path against a regular
expression and deriving the intended alias by expanding placeholders (${name},
$1, etc.) with the corresponding submatches from the import path. Example:
k8s.io/kubernetes/test/e2e/framework/([^/]*) -> e2e$1
This support is backwards compatible because normal import paths don't contain
characters that are special in a regular expression and normal aliases don't
contain placeholders.
A regular expression must match the entire import path, otherwise it is
skipped.
Track how long it takes for pod updates to propagate from detection
to successful change on API server. Will guide future improvements
in pod start and shutdown latency.
Metric is `kubelet_pod_status_sync_duration_seconds` and is ALPHA
stability. Histogram buckets are chosen based on distribution of
observed status delays in practice.
Fix the one path where boundNextDispatchLocked was not being called
after modifying a queue.
Also check for negative work in a request.
These are motivated by
https://github.com/kubernetes/kubernetes/issues/112169 but I do not
have a way to reproduce it and so can not check that these changes
actually remove that symptom. But these changes are good anyway.
The use of `kubectl_complete-ns` enables shell completion when calling
the plugin through `kubectl ns`. The script only completes flag names
and namespace arguments.

When doing completion for arguments or flags for a plugin, kubectl will
call "kubectl_complete-<plugin>" to obtain the list of completions.
For example, for "krew" plugin, when the user triggers completion using:
$ kubectl krew <tab><tab>
kubectl will look for an executable file called "kubectl_complete-krew".
This file should print the list of valid completions for the plugin to
stdout. Using cobra.ShellCompDirective as the last line of the output
is supported as is done by Cobra.
We also clear global flags when doing plugin completion because plugins
don't necessarily accept the global kubectl flags. If some plugins do,
they will need to include such flags in their kubectl_complete-<plugin>
output.
