61d05dea58 Allow to specify number of concurrent DNS queries 
ndots creates overhead as every pod creates 5 concurrent connections
that are forwarded to sky dns. Under some circumstances dnsmasq may
prevent forwarding traffic with "Maximum number of concurrent DNS
queries reached" in the logs.

This patch allows to configure the number of concurrent forwarded DNS
queries "dns-forward-max" as well as "cache-size" leaving the default
values as they were before.

6c69da1573 This PR adds/or modifies a few tasks to allow for the playbook to 
be run by limit on each node without regard for order.

The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node.  This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.

95bf380d07 If the inventory name of the host exceeds 63 characters, 
the openssl tools will fail to create signing requests because
the CN is too long.  This is mainly a problem when FQDNs are used
in the inventory file.

THis will truncate the hostname for the CN field only at the
first dot.  This should handle the issue for most cases.

f77257cf79 When running on CentOS7 image in AWS with selinux on, the order of 
the tasks fail because selinux prevents ip-forwarding setting.

Moving the tasks around addresses two issues.  Makes sure that
the correct python tools are in place before adjusting of selinux
and makes sure that ipforwarding is toggled after selinux adjustments.

still have to resolve external or intranet FQDNs.
