Removed tripleo-common checkout/fetch

There was a patch that was fetching instead of cherry-picking
in tripleo-common. This was causing us to use some old tripleo-common
code... thus causing config-download failures
"expected a character buffer object" issues. This removes the
patch as it was not required for the underclouds use of this feature.
