* Defaults for apiserver_loadbalancer_domain_name
When loadbalancer_apiserver is defined, use the
apiserver_loadbalancer_domain_name with a given default value.
Fix unconsistencies for checking if apiserver_loadbalancer_domain_name
is defined AND using it with a default value provided at once.

* Define defaults for LB modes in common defaults
Adjust the defaults for apiserver_loadbalancer_domain_name and
loadbalancer_apiserver_localhost to come from a single source, which is
kubespray-defaults. Removes some confusion and simplefies the code.

* Add possibility to insert more ip adresses in certificates
* Add newline at end of files
* Move supp ip parameters to k8s-cluster group file
* Add supplementary addresses in kubeadm master role
* Improve openssl indexes
Also adds all masters by hostname and localhost/127.0.0.1 to
apiserver SSL certificate.
Includes documentation update on how localhost loadbalancer works.
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.
