1b1f5f22d4 Fix etcd standalone deployment
etcd facts are generated in kubernetes/preinstall, so etcd nodes need
to be evaluated first before the rest of the deployment.

Moved several directory facts from kubernetes/node to
kubernetes/preinstall because they are not backward dependent.

7a86b6c73e Set default etcd deployment to docker
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.

32cd6e99b2 Add etcd proxy support
* 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

b3282cd0bb Add optional deployment mode for Docker etcd_deployment_type
Running etcd in Docker reduces the number of individual file
downloads and services running on the host.

Note: etcd container v3.0.1 moves bindir to /usr/local/bin

Fixes: #298

0500f27db8 Scale-up functionality for etcd cluster
* Set ETCD_INITIAL_CLUSTER_STATE from `new` to `existing`,
because parameter `new` makes sense only on cluster assembly
stage.
* If cluster exists and current node is not a part
of the cluster, add it with command `etcdctl add member name url`.

Closes kubespray/kargo/#270

180f2d1fde Pull correct variable for etcd initial variable
This shouldn't use the `inventory_hostname` variable, as that will just yield the same variable, but rather use the `host` which we're looping over.

47982ea21c Use ansible array format instead of dot-notation.
This fixes the ansible error ```'dict object' has no attribute
'ansible_default_ipv4'"}```. Closes #215

bedcca922c Add variables and defaults for multiple types of ip addresses.
Each node can have 3 IPs.
1. ansible_default_ip4 - whatever ansible things is the first IPv4 address
   usually with the default gw.
2. ip - An address to use on the local node to bind listeners and do local
   communication.  For example, Vagrant boxes have a first address that is the
   NAT bridge and is common for all nodes.  The second address/interface should
   be used.
3. access_ip - An address to use for node-to-node access.  This is assumed to
   be used by other nodes to access the node and may not be actually assigned
   on the node.  For example, AWS public ip that is not assigned to node.

This updates the places addresses are used to use either ip or access_ip and walk
up the list to find an address.
