Deploy a default StorageClass instance on AWS and GCE
This needs a newer kubectl in kube-addons-manager container. It's quite tricky to test as I cannot push new container image to gcr.io and I must copy the newer container manually.

**Release note**:
```release-note
Kubernetes now installs a default StorageClass object when deployed on AWS, GCE and
OpenStack with kube-up.sh scripts. This StorageClass will automatically provision
a PeristentVolume in corresponding cloud for a PersistentVolumeClaim that cannot be
satisfied by any existing matching PersistentVolume in Kubernetes.
To override this default provisioning, administrators must manually delete this default StorageClass.

Remove several red herring error messages in GCE cluster scripts
This fixes things like

It seems like the `kubectl` behavior was introduced in #29236: if `current-context` is set to something invalid, it now complains.
This should avoid spamming build-log.txt with messages like:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
OSX has shasum but not sha1sum, which is part of GNU coreutils.

WIP: Remove the legacy networking mode
<!-- Thanks for sending a pull request! Here are some tips for you:

**What this PR does / why we need it**:
Removes the deprecated configure-cbr0 flag and networking mode to avoid having untested and maybe unstable code in kubelet, see: #33789
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
fixes#30589fixes#31937
**Special notes for your reviewer**: There are a lot of deployments who rely on this networking mode. Not sure how we deal with that: force switch to kubenet or just delete the old deployment?
But please review the code changes first (the first commit)
**Release note**:
<!-- Steps to write your release note:
1. Use the release-note-* labels to set the release note state (if you have access)
2. Enter your extended release note in the below block; leaving it blank means using the PR title as the release note. If no release note is required, just write `NONE`.

Enable the garbage collector by default
Turning GC on by default.
Memory usage of GC is back to normal after #30943. The CPU usage is a little higher than the cap in scalability test (1.11 core vs. 1 core). This PR adjusted the default GC worker to 20 to see if that helps CPU usage.

Add support for kube-up.sh to deploy Calico network policy to GCI masters
Also remove requirement for calicoctl from Debian / salt installed nodes and clean it up a little by deploying calico-node with a manifest rather than calicoctl. This also makes it more reliable by retrying properly.
How to use:
```
make quick-release
NETWORK_POLICY_PROVIDER=calico cluster/kube-up.sh
```
One place where I was uncertain:
- CPU allocations (on the master particularly, where there's very little spare capacity). I took some from etcd, but if there's a better way to decide this, I'm happy to change it.

* Add a pillar for hostname (because even if there's a good Salt
function for it, I don't trust it to return the short hostname)
* Move INITIAL_ETCD_CLUSTER to just the GCE turn-up
* Remove the master_name, which isn't needed as a pillar
