use nginx proxy on non-master nodes to proxy apiserver traffic Also adds all masters by hostname and localhost/127.0.0.1 to apiserver SSL certificate. Includes documentation update on how localhost loadbalancer works.

manage undefined vars for loadbalancing

fix load balancer DNS name index evaluation in openssl.conf Looks like OpenSSL still properly handles it, even with duplicated "DNS.X" items.

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.
