Systemd in rhel7.2 is not picking up proxy configs

[jamesdboone]

Looks like docker service doesn't pick up the proxy environment vars.

no_proxy='myreg.url.com,myreg.url.com'

This is also a handy place to tweak where Docker's temporary files go.

I resolved this by adding to bottom of 'service-overrides-rhel.conf.erb':
<% if @Proxy %>Environment="HTTP_PROXY=<%= @Proxy %>" "HTTPS_PROXY=<%= @Proxy %>"<% if @no_proxy %> "NO_PROXY=<%= @no_proxy %>"<% end %><% end %>
