Removes unnecessary/incorectly-named packages from HDP install script

This patch fixes bug 1292519.  Some install packages were listed
  that were not available in the repositories used for the HDP
  image installs.
Some of these packages were only valid for HDP 1.3, and so have
  been removed from the HDP 2.0 install commands.
Some of the packages listed in the HDP 1.3 install were only valid
  in HDP 2.0, so these package names have been removed from the
  HDP 1.3 install.
Some packages in the HDP 1.3 install commands were incorrectly named
  and not actually required by HDP 1.3, so this patch removes those
  package names.
The commands used to install mysql have been refactored into a
  common method, which is now used by both the HDP 1.3 and 2.0
  installs.
This patch also removes other unavailable packages that were listed
  in warnings during the HDP image generation process.  After some
  investigation, it was determined that these packages were either
  incorrectly referenced, or no longer needed for HDP.
