Automatic merge from submit-queue

Run node e2e pull VMs in a separate GCP project

I haven't increased quota yet, so we shouldn't merge until I've done so. This is mostly just testing to see if the rest of the plumbing works.

Part of #27648.

[GarbageCollector] measure latency

First commit is #27600.

In e2e tests, I measure the average time an item spend in the eventQueue(~1.5 ms), dirtyQueue(~13ms), and orphanQueue(~37ms). There is no stress test in e2e yet, so the number may not be useful.

Simplify canonical element term in deepcopy

Replace the old functional canonical element term in deepcopy registration with direct struct instantiation.

The old way was an artifact of non-uniform pointer/non-pointer types in the signature of deepcopy function. Since we changed that to always be a pointer, we can simplify the code.

Support custom Fedora repos in vagrant provider

Sometimes `KUBERNETES_PROVIDER=vagrant cluster/kube-up.sh` fails due to problems
with Fedora's metalink URL:
```
Timeout was reached for https://mirrors.fedoraproject.org/metalink?repo=fedora-23&arch=x86_64 [Connection timed out after 120002 milliseconds]
```

This PR makes it possible to specify a custom Fedora repository URL:
```
export CUSTOM_FEDORA_REPOSITORY_URL=https://download.fedoraproject.org/pub/fedora/
```

`release_not_found` shell function can be used both while running
`provision-master.sh` and `privision-node.sh` (it's used by `install-salt`
function in `provision-utils.sh`, but it was defined in `provision-master.sh`.
Because of this, one of my colleagues got the following diagnostic:

```
==> master: Succeeded: 52 (changed=8)
==> master: Failed:     0
==> master: -------------
==> master: Total states run:     52
==> node-1: Machine already provisioned. Run `vagrant provision` or use the `--provision`
==> node-1: flag to force provisioning. Provisioners marked to run always will still run.
==> node-1: Running provisioner: shell...
    node-1: Running: /tmp/vagrant-shell20160726-19144-hahnl1.sh
==> node-1: Prepare package manager
==> node-1: Provisioning network on node
==> node-1: Network configuration verified
==> node-1: /tmp/vagrant-shell: line 134: release_not_found: command not found
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
```
... which is rather confusing.

AWS: Allow no-op kube-down to exit 0

Not exactly sure why hack/e2e.go `IsUp()` is returning true right now,
but I can solve this a different way. This unifies with the GCE
behavior, which is that no-op kube-down returns 0.
