2d6bc9536c Merge pull request #1246 from holser/disable_dns_for_kube_services 
Change DNS policy for kubernetes components

01dc6b2f0e Add aws to default_resolver 
When VPC is used, external DNS might not be available. This patch change
behavior to use metadata service instead of external DNS when
upstream_dns_servers is not specified.

d8aa2d0a9e Change DNS policy for kubernetes components 
According to code apiserver, scheduler, controller-manager, proxy don't
use resolution of objects they created. It's not harmful to change
policy to have external resolver.

1cfe0beac0 Set ClusterFirstWithHostNet for Pods with hostnetwork: true 
In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.

This patch sets the same resolv.conf for kubelet as host

c4e57477fb replace non-breakable space with regular space 
Non-brekable space is 0xc2 0xa0 byte sequence in UTF-8.

To find one:

    $ git grep -I -P '\xc2\xa0'

To replace with regular space:

    $ git grep -l -I -P '\xc2\xa0' | xargs sed -i 's/\xc2\xa0/ /g'

3a39904011 Move calico-policy-controller into separate role 
By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.

K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.

This patch also fixes kube-api port in calico-policy-controller
yaml template.

Closes #1132
