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.

Gce persistentvolume testing
Add E2E PersistentVolume test for a GCE environment. Tests that deleting a PV or PVC before the referencing pod does not fail on unmount and detach during pod deletion.

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.
This update includes significant refactoring. It moves almost all of the
logic into bash scripts, modeled after the `gci` cluster scripts.
The primary differences between the two are the following:
1. Use of the `/opt/kubernetes` directory over `/home/kubernetes`
2. Support for rkt as a runtime
3. No use of logrotate
4. No use of `/etc/default/`
5. No logic related to noexec mounts or gci-specific firewall-stuff

@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.

[Federation] Remove unnecessary functions from develop.sh as part of …
This is part of a big refactor to deprecate a short-lived deploy.sh
mechanism that nobody really could use due to bugs.
```release-note
`federation/deploy/deploy.sh` was an interim solution introduced in Kubernetes v1.4 to simplify the federation control plane deployment experience. Now that we have `kubefed`, we are deprecating `deploy.sh` scripts.

local-up-cluster additions
**What this PR does / why we need it**:
Changes to local-cluster-up: These include: 1) a simple additional help option. 2) additional error message to not being able to run `docker ps`. 3) fail faster when etcd is not found in path. Hopefully these make developing a bit more pleasant.

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.
