Users can pass resources into `kubectl events` command via `--for` flag,
if they have desire to only get events for the resource they specify.
However, current `kubectl events` does not support passing fully qualified
names(e.g. `replicasets.apps`, `cronjobs.v1.batch`, etc.). This PR adds support
for this.

To improve wall-clock speed, we run list operations in parallel. This
particularly helps when the round-trip time is high.
We issue requests as quickly as possible, kube-apiservers should all
have priority and fairness at this point and we don't want to
duplicate/fight that system.

This PR sets higher priority to the `share-processes` flag than
provided profile.
For example, if user tries to use copy-to debugging with restricted
profiling, share process namespace should be false if user explicitly
disables it via `--share-processes=false`.

Removes the need to pass cmd as an argument to Run(). This change required reading the --sort-by flag in Complete() in a way similar to other flags.
This change allows the cobra.Command not to need to be passed throughout the completion code, which I updated as part of this commit.
It also is a step in the direction of the TODO comment requesting the removal of arguments passed to Run() and watch().

* ensure pod copies always get their probes cleared
not wanting probes to be present is something we want
for all the debug profiles; so an easy place to implement
this is at the time of pod copy generation.
* ensure debug container in pod copy is added before the profile application

debug container to be added after the profile applier runs. We now
make sure to have the container list modification happen before
the profile applier runs.

`rollout restart` command calculates patches according to the
`kubectl.kubernetes.io/restartedAt` annotation whose time format is
RFC3339. That is sufficient for users. However, if automated scripts
execute `rollout restart` in multiple times within second, commands fails
by returning an error "empty patch".
This PR changes error message to more descriptive format to warn users
that rollout restart does not work subsequent execution within second.

the sameGVK multiple times for --allow-whitelist. Now it only attempts to

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.

This commit allows us to get shell completion for kubectl plugins.
For example, with the use of a plugin named 'kubectl-krew', completing
kubectl k<tab>
will include 'krew' in the list of possible completions.
Because the shell completion scripts are generated by Cobra, this commit
took the approach of registering every plugin as a Cobra command. This
makes Cobra aware of each plugin command when generating completions.
For efficiency, searching for plugins and registering them as Cobra
commands is only done when needed, which is when calling the
'kubectl completion' command in the case of bash, as it includes all
commands and subcommands directly in the bash generated script.
For the other shells, this will need to be done for the
'kubectl __complete' command, in a follow-up command.
