syntax for secondary-ranges changed from:
name=NAME,range=RANGE
to
NAME=RANGE
proxy_handler now uses the endpoint router to map the cluster IP to
appropriate endpoint (Pod) IP for the given resource.
Added code to allow aggregator routing to be optional.
Updated bazel build.
Fixes to cover JLiggit comments.
Added util ResourceLocation method based on Listers.
Fixed issues from verification steps.
Updated to add an interface to obfuscate some of the routing logic.
Collapsed cluster IP resolution in to the aggregator routing
implementation.
Added 2 simple unit tests for ResolveEndpoint
Setting this will trigger
cluster/addons/ip-masq-agent/ip-masq-agent.yaml to be installed as an
addon, which disable configure IP masquerade for all of RFC1918, rather
than just 10.0/8.

kube-proxy: ratelimit runs of iptables by sync-period flags
This bounds how frequently iptables can be synced. It will be no more often than every 10 seconds and no less often than every 1 minute, by default.

GCE - Retrieve subnetwork name/url from gce.conf
**What this PR does / why we need it**:
Features like ILB require specifying the subnetwork if the network is type manual.
**Notes:**
The network URL can be [constructed](68e7e18698/pkg/cloudprovider/providers/gce/gce.go (L211-L217)) by fetching instance metadata; however, the subnetwork is not provided through this feature. Users must specify the subnetwork name/url through the gce.conf.
Although multiple subnets can exist in the same region for a network, the cloud provider will only use one subnet url for creating LBs.
**Release note**:

NONE

A daemonset deployment is included to make it easy to consume the installer
A cluster e2e has been added to test the installation daemonset along with verifying installation
by using a sample CUDA application.
Node e2e for GPUs updated to avoid running on nodes without GPU devices.

Update Calico add-on
**What this PR does / why we need it:**
Updates Calico to the latest version using self-hosted install as a DaemonSet, removes Calico's dependency on etcd.
- [x] Remove [last bits of Calico salt](175fe62720/cluster/saltbase/salt/calico/master.sls (L3))
- [x] Failing on the master since no kube-proxy to access API.
- [x] Fix outgoing NAT
- [x] Tweak to work on both debian / GCI (not just GCI)
- [x] Add the portmap plugin for host port support
Maybe:
- [ ] Add integration test

Enable kernel memcg notification for node and cluster GCI/COS testing.
Sets --experimental-kernel-memcg-notification=true when running on the GCI/COS image. It sets this for master and nodes for cluster e2e tests, and for the node in node e2e tests.

IP aliases are an alpha feature, and node accelerators are a beta
feature. $gcloud determines which is appropriate.
Before, this would try to run "gcloud alpha beta", which is incoherent.

Update repo-infra bazel dependency and use new gcs_upload rule
This PR provides similar functionality to push-build.sh entirely within Bazel rules (though it relies on gsutil).
It's an alternative to #44306.
Depends on https://github.com/kubernetes/repo-infra/pull/13.
**Release note**:
```release-note
NONE
```
Using Ubuntu on GCE to run cluster e2e tests requires slightly different
node.yaml and master.yaml files than GCI, because Ubuntu uses systemd as
PID 1, wheras GCI uses upstart with a systemd delegate. Therefore the
e2e tests fail using those files since the kubernetes services are not
brought back up after a node/master reboot.

Add support for IP aliases for pod IPs (GCP alpha feature)
```release-note
Adds support for allocation of pod IPs via IP aliases.
# Adds KUBE_GCE_ENABLE_IP_ALIASES flag to the cluster up scripts (`kube-{up,down}.sh`).
KUBE_GCE_ENABLE_IP_ALIASES=true will enable allocation of PodCIDR ips
using the ip alias mechanism rather than using routes. This feature is currently
only available on GCE.
## Usage
$ CLUSTER_IP_RANGE=10.100.0.0/16 KUBE_GCE_ENABLE_IP_ALIASES=true bash -x cluster/kube-up.sh
# Adds CloudAllocator to the node CIDR allocator (kubernetes-controller manager).
If CIDRAllocatorType is set to `CloudCIDRAllocator`, then allocation
of CIDR allocation instead is done by the external cloud provider and
the node controller is only responsible for reflecting the allocation
into the node spec.
- Splits off the rangeAllocator from the cidr_allocator.go file.
- Adds cloudCIDRAllocator, which is used when the cloud provider allocates
the CIDR ranges externally. (GCE support only)
- Updates RBAC permission for node controller to include PATCH
```
KUBE_GCE_ENABLE_IP_ALIASES=true will enable allocation of PodCIDR ips
using the ip alias mechanism rather than using routes.
NODE_IP_RANGE will control the node instance IP cidr
KUBE_GCE_IP_ALIAS_SIZE controls the size of each podCIDR
IP_ALIAS_SUBNETWORK controls the name of the subnet created for the cluster

hack/cluster: download cfssl if not present
hack/local-up-cluster.sh uses cfssl to generate certificates and
will exit it cfssl is not already installed. But other cluster-up
mechanisms (GCE) that generate certs just download cfssl if not
present. Make local-up-cluster.sh do that too so users don't have
to bother installing it from somewhere.
