Trusty: fix the 'ping' issue and fluentd-gcp issue #26379
This PR is mainly for being picking up the fix in #27016 and #27102 in trusty code, so that we can fix the issues in the release-1.2 branch for GCI. It contains two parts:
(1) Adding iptables rules to accept ICMP traffic, otherwise 'ping' from a pod does not work;
(2) Revising the code for cleaning up docker0 stuff including the bridge and iptables rules. I slightly refactor the code of starting kubelet and removing docker0 stuff before starting kubelet. The old code did it after starting kubelet but before restarting docker. I think doing it before starting kubelet is safter.

cluster/gce/coreos: Update heapster apiVersion
This fixes an inadvertant search-replace error in #26617.
The error was missed then because the search-replace issue wasn't
present in the standalone controllers, but was in all the others.
I verified that with this change heapster comes up under the default influxdb monitoring and without this change addon manager spits out validation failure errors for the heapster yaml.

GCI: correct the fix in #26363
This PR is mainly for correcting the fix to 'find' command in #26363. I added "-maxdepth 1" in an earlier change, and #26363 tried to fix it by changing the search path. This is potentially incorrect, when yaml files are in more than one layer deep. The real fix should be removing the "-maxdepth 1" flag from 'find' command. This PR also updates two minor places in the file configure-helper.sh introduced by two previous PR #26413 and #26048.

This makes it so that we download the OS image automatically.
Also contains other usability improvements:
- kubectl context created with heat stack name
- Bumped default minions to 3
Making the assumption that the person running kube-up has their
Openstack environment setup, those same variables are being passed
into heat, and then into openstack.conf.
The salt codebase was modified to add openstack as well.
If someone has an openrc as part of their profile, this will make kube-up work automatically.
The only things that have to be modified are in config-default.sh, either by editing the file or setting environment variables.
This assumes you have your environement variables set correctly.
When ENABLE_PROXY is set to true, it takes the current proxy
settings and applies them to the heat configuration.
Also modified the defaults system in config-default.sh

that it needs to talk to the apiserver. This will also improve other
pods that require service accounts.
* Add routes to the master so it can communicate with the pods, so
hitting the https://MASTER/ui URL will allow it to contact the
pods.
* Add an extra subject for the cluster IP to the apiserver, so when
the dashboard communicates with the apiserver, the certificate
matches the IP address it's using.

Trusty: Add debug supports for docker and kubelet
This PR adds debug support in two aspects: (1) For a test cluster, docker command will have "--debug" flag. Recently we noticed that this is very helpful in debug e2e test failures; (2) The kubelet command line will be put in /etc/default/kubelet. If a developer wants to test kubelet flags without recreating a cluster, she/he only needs to revise this file and then run "initctl restart kubelet". In addition, this PR fixes a couple of small things like comments and alignment.
Test result:
(1) Manually verified changing /etc/default/kubelet and run "initctl restart kubelet";
(2) Verified docker command line flag "--debug";
(3) e2e on pure trusty cluster and hybrid cluster all passed.

Initial kube-up support for VMware's Photon Controller
This is for: https://github.com/kubernetes/kubernetes/issues/24121
Photon Controller is an open-source cloud management platform. More
information is available at:
http://vmware.github.io/photon-controller/
This commit provides initial support for Photon Controller. The
following features are tested and working:
- kube-up and kube-down
- Basic pod and service management
- Networking within the Kubernetes cluster
- UI and DNS addons
It has been tested with a Kubernetes cluster of up to 10
nodes. Further work on scaling is planned for the near future.
Internally we have implemented continuous integration testing and will
run it multiple times per day against the Kubernetes master branch
once this is integrated so we can quickly react to problems.
A few things have not yet been implemented, but are planned:
- Support for kube-push
- Support for test-build-release, test-setup, test-teardown
Assuming this is accepted for inclusion, we will write documentation
for the kubernetes.io site.
We have included a script to help users configure Photon Controller
for use with Kubernetes. While not required, it will help some
users get started more quickly. It will be documented.
We are aware of the kube-deploy efforts and will track them and
support them as appropriate.

Trusty: Add retry in curl commands
This fix is for improving robustness in fetch critical metadata files when the metadata server is temporarily unreachable.

Use kube-system namespace
Fixes#23153.
Sadly, kube-system isn't automatically created, so people need to make
sure to create it in their turnup scripts. Also after creating
kube-system it can take 10+ seconds for master and proxy to show up.
I tested the equivalent of these changes locally, but not these changes
themselves as I don't have a dev/build env up, so please read carefully
and maybe try them out!

E2e shows occasional kubectl failures here, so add some retries. We may want
to make this more general, but I think we should try it out in small scope
first.
Also clean up the retry loop so it doesn't process errors as successful runs
(discovered in testing).
Also simplify a bit of go template syntax.
Testing: I made kubectl randomly fail 50% of the time ($RANDOM%2 ==0) and
iterated until this gave me more helpful results. Still not perfect, but
better.

jenkins: Allow configuration of release bucket
This allows others to leverage the existing E2E code to test some
patched kube binary by simply overriding the bucket and reusing many of
the existing scripts
