In new `calicoctl` version nodes peering with routers is broken.
We need to use predictable node names for calico-node and the
same names in calico `bgpPeer` resources and CNI.
Since version 'v1.0.0-beta' calicoctl is written
in Go and its API differs from old Python based
utility. Added support of both old and new version
of the utility.

- Allow to overwrite calico cni binaries copied from hyperkube
by the custom ones.
- Fix calico-ipam deployment (it had wrong source in rsync)
- Make copy from hyperkube idempotent (use rsync instead of cp)
- Remove some orphaned comments
* Add the retry_stagger var to tweak push and retry time strategies.
* Add large deployments related docs.

Hyperkube from CoreOS now ships with all binaries required for
calico and flannel (but not weave). It simplifies deployment for
some network plugin scenarios to not download CNI images.
TODO: Optionally disable downloading calico to /opt/cni/bin
Creating the unit using default settings early on
and then changing it during network_plugin section
leads to too many docker restarts and duplicated code.
Reversed Wants= dependence on docker.service so it does not
restart docker when reloading systemd
Consolidated all docker restart handlers.
Adds new boolean configuration variable for calico network plugin
`ipip`. When it's enabled calico pool is created with '--ipip'
option (IP-over-IP encapsulation across hosts).
Also refactor pool creation tasks to simplify logic and make tasks
more readable.
Improved docker reload command to wait for etcd to be
up before proceeding. Switched reload to run restart
because it can't reload if it is not guaranteed to be
in running state.
* Enforce a etcd-proxy role to a k8s-cluster group members. This
provides an HA layout for all of the k8s cluster internal clients.
* Proxies to be run on each node in the group as a separate etcd
instances with a readwrite proxy mode and listen the given endpoint,
which is either the access_ip:2379 or the localhost:2379.
* A notion for the 'kube_etcd_multiaccess' is: ignore endpoints and
loadbalancers and use the etcd members IPs as a comma-separated
list. Otherwise, clients shall use the local endpoint provided by a
etcd-proxy instances on each etcd node. A Netwroking plugins always
use that access mode.
* Fix apiserver's etcd servers args to use the etcd_access_endpoint.
* Fix networking plugins flannel/calico to use the etcd_endpoint.
* Fix name env var for non masters to be set as well.
* Fix etcd_client_url was not used anywhere and other etcd_* facts
evaluation was duplicated in a few places.
* Define proxy modes only in the env file, if not a master. Del
an automatic proxy mode decisions for etcd nodes in init/unit scripts.
* Use Wants= instead of Requires= as "This is the recommended way to
hook start-up of one unit to the start-up of another unit"
* Make apiserver/calico Wants= etcd-proxy to keep it always up
