Curating Owners: cluster/juju
cc @castrojo @mbruzek @chuckbutler @marcoceppi
In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

add service status detection to kubernetes-discovery
This adds an inspection of services and endpoints before adding the APIService to kubernetes-discovery. This keeps a single bad API service from killing old clients since proxying will fail.

Prevent json decoder panic on invalid input

```
# Can be replicated on kubectl with:
$ cat panic.json
{
"kind": "Pod",
"apiVersion": "v1",
"metadata": {
"name": "",
"labels": {
"name": ""
},
"generateName": "",

},
"spec": {}
},
$ kubectl create -f panic.json --validate=false
```
**Release note**:
```release-note
release-note-none
```
This patch handles cases where `ioutil.ReadAll` will return a single
character output on an invalid json input, causing the `Decode` method
to panic when it tries to calculate the line number for the syntax
error. The example below would cause a panic due to the trailing comma
at the end:
```
{
"kind": "Pod",
"apiVersion": "v1",
"metadata": {
"name": "",
"labels": {
"name": ""
},
"generateName": "",
"namespace": "",
"annotations": []
},
"spec": {}
},
```

Refactor port allocation logic a little, deflake tests.
This should fix#38323 for real.
@xiangpengzhao @rmmh @justinsb
Switch to manually cranking over the port filling logic, since there was a race between the allocate logic and the check to see if the port was freed up.

Not all clientconfigs require negotiation. Before there was a patch (hardcoded to an instance variable) that allowed this. This updates the code to allow the same as before.

Reduce amount of allocations in cacher
Currently we are unnecessary copying stuff around in cacher.
This results in __tens of megabytes__ of allocations per __second__ in large clusters. This in turn results in expensive GC. Should help with metrics.

conversion-gen: add --skip-unsafe flag
We should expose the SkipUnsafe option, for legacy compatability, so
that conversion-go can be used in other projects, and for platforms
where unsafe is not available.
Make unsafe code generation the default though, and have the help text
hint that the resulting code is sub-optimal.

@ethernetdan has also volunteered as well (thanks!).

Remove two zany unit tests.
These two tests aren't unit tests in the usual sense. We can consider switching them to run as verify checks, but I'm not convinced that they're even necessary.
They essentially work by searching their code for public functions with signatures that look like `FitPredicate`, then they shell out to grep to see that they're used somewhere in the source tree. This will never work in bazel.

Adds e2e firewall tests for LoadBalancer service, ingress, and e2e cluster
Fixes#25488 and fixes#31827.
This PR adds e2e firewall test for LoadBalancer type service, ingress and e2e cluster.
Test details for LoadBalancer type service as below:
- Verifies corresponding firewall rule has correct `sourceRanges`, `ports and protocols` and `target tags`.
- Verifies requests can reach all expected instances.
- Verifies requests can not reach instances that are not included.
Overview of the test procedure:
- Creates a LoadBalancer type service.
- Validates the corresponding firewall rule.
- Creates netexec pods as service backends.
- Sends requests from outside of the cluster and examine hitting all instances in range.
- Removes tags from one of the instances in order to get it out of firewall rule's range.
- Sends requests from outside of the cluster and examine not hitting this instance.
- Recovers tags for this instances and verifies its traffic is back.

rename constant MaxPatchConflicts to maxRetryWhenPatchConflicts
**What this PR does / why we need it**:
1. literally `MaxPatchConflicts` means max number of patch conflicts allowed during a patch operation. but actually in codes it is used to indicate max number of patch retry when patch conflicts happened.
2. there is no need to export this constant because it is only used in `resthandler.go` and shouldn't be used in other packages.
