Update core etcd references to use 3.0.4
This updates the core references to use 3.0.4.
There are still legacy references in the code base that should be cleaned, or just removed but I'm reluctant to purge.

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
we need to add the dateformat option so that the logrotate
can create unique logfiles for each rotation. Without this,
we logrotation is skipped with message like (generated in
verbose mode of logrotate):
rotating log /var/log/rotate-test.log, log->rotateCount is 5
dateext suffix '-20160718'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
destination /var/log/rotate-test2.log-20160718.gz already exists, skipping rotation
Tested as follows:
# config in '/etc/logrotate.d/rotate-test':
/var/log/rotate-test.log {
rotate 5
copytruncate
missingok
notifempty
compress
maxsize 100M
daily
dateext
dateformat -%Y%m%d-%s
create 0644 root root
}
# create 150Mb of /var/log/rotate-test.log
$ dd if=/dev/zero of=/var/log/rotate-test.log bs=1048576 count=150 conv=notrunc oflag=append
# run logrotate
$ /usr/sbin/logrotate -v /etc/logrotate.conf
...
rotating pattern: /var/log/rotate-test.log after 1 days (5 rotations)
empty log files are not rotated, log files >= 104857600 are rotated earlier, old logs are removed
considering log /var/log/rotate-test.log
log needs rotating
rotating log /var/log/rotate-test.log, log->rotateCount is 5
Converted ' -%Y%m%d-%s' -> '-%Y%m%d-%s'
dateext suffix '-20160718-1468875268'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
copying /var/log/rotate-test.log to /var/log/rotate-test.log-20160718-1468875268
truncating /var/log/rotate-test.log
compressing log with: /bin/gzip
Repeating 'dd' and 'logrotate' commands now generate logfiles correctly.

kube-up: install new Docker pre-requisite (libltdl7) when not in image
Docker now has a dependency on libltdl7; we have to specify it manually
if we are installing docker using dpkg (vs using apt-get or similar,
which would pull it in automatically)
Fixes#28644

Bump skydns godeps to latest
Update Godeps for github.com/skynetservices/skydns and miekg/dns.
Bump kubedns version to 1.6 with latest skynetservices/skydns code
Built kube-dns for all architectures and pushed containers to gcr.io.

Enhance kubedns pod health checks to cover kubedns container
The existing health check hits port 53, the dnsmasq container, with the same domain name every time. Since dnsmasq looks up and caches results from the kubedns container, running on port 10053, the health check is not covering the kubedns container after the first query (and once every TTL expiration).
This PR enhances the health check to directly hit port 10053 (kubedns) in addition to port 53.

Remove duplicated nginx image. Use nginx-slim instead
This PR removes the image `gcr.io/google_containers/nginx:1.7.9` and uses `gcr.io/google_containers/nginx-slim:0.7`.
Besides removing the duplication `1.7.9` is 16 months old.

Enable setting up Kubernetes cluster in Ubuntu on Azure
Implement basic cloud provider functionality to deploy Kubernetes on
Azure. SaltStack is used to deploy Kubernetes on top of Ubuntu
virtual machines. OpenVpn provides network connectivity. For
kubelet authentication, we use basic authentication (username and
password). The scripts use the legacy Azure Service Management APIs.
We have set up a nightly test job in our Jenkins server for federated
testing to run the e2e test suite on Azure. With the cloud provider
scripts in this commit, 14 e2e test cases pass in this environment.
We plan to implement additional Azure functionality to support more
test cases.
