Remove the ability to add update properties

[decelc-pivotal]

A tile developer can define update properties:

  canaries: 2
  canary_watch_time: 3600000-7200000
  max_in_flight: 10
  update_watch_time: 3600000-7200000

but they get overwritten by Ops Mgr when the tile is installed - https://github.com/pivotal-cf/installation/blob/master/web/app/models/tempest/manifests/product_manifest_generator.rb#L223-L232

def update_section
     {
       'canaries' => 1,
       'canary_watch_time' => '30000-300000',
       'update_watch_time' => '30000-300000',
       'max_in_flight' => 1,
       'max_errors' => 2,
       'serial' => @product.template.serial,
     }
end

We should remove the ability of adding these properties.
