Run cAdvisor on the same interface as kubelet

**What this PR does / why we need it**:

cAdvisor currently binds to all interfaces. Currently the only
solution is to use iptables to block access to the port. We
are better off making cAdvisor to bind to the interface that
kubelet uses for better security.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

Fixes #11710

**Special notes for your reviewer**:

**Release note**:

```release-note
cAdvisor binds only to the interface that kubelet is running on instead of all interfaces.

Remove limits from ip-masq-agent for now and disable ip-masq-agent in GCE

ip-masq-agent when issuing an iptables-save will read any configured iptables on the node.  This means that the ip-masq-agent's memory requirements would grow with the number of iptables (i.e. services) on the node.

Add git branch to make build short hash unique

**What this PR does / why we need it**:

KUBE_ROOT_HASH depends just on the host name and
directory path. So when working with branches, it could lead
to some confusion since the hash is the same even when
you switch from branch to branch. Let us use the git branch
information when we compute the short hash

Move govet verify into rest of verify*-.sh scripts

**What this PR does / why we need it**:
Instead of having two govet scripts, consolidate them to into one and have both the Makefile and verify.sh scripts target the same script. This also will allow proper syntax highlighting and timing when the vet script is run as part of `make verify`.

Give developer more help info when running integration tests without etcd found.

**What this PR does / why we need it**:
When running integration tests, if etcd version on env is lower than expected, developer will get info `You can use 'hack/install-etcd.sh' to install a copy in third_party/.` It would be better to have the same info if no etcd installed on env.
