Add global proxy configuration

Configures HTTP_PROXY, HTTPS_PROXY, NO_PROXY for master and docker services.
Configugres BuildDefaults Admission controller for master to automatically
insert proxy environment configuration into build environments.

To use set at least these variables
  - openshift_http_proxy
  - openshift_https_proxy

NO_PROXY entries will automatically be configured for hostnames of all openshift
hosts. You may specify additional NO_PROXY hosts or patterns by setting
`openshift_no_proxy`

If you wish to disable automatic generation of NO_PROXY hosts you may set
`openshift_generate_no_proxy_hosts` to False.

If you wish to have different builddefaults proxy configuration than baseline
proxy configuration set these variables
  - openshift_builddefaults_http_proxy
  - openshift_builddefaults_https_proxy
  - openshift_builddefaults_no_proxy
  - openshift_builddefaults_git_http_proxy
  - openshift_builddefaults_git_https_proxy
