bypass_satsolver_on_install
============================
This method is used to run the conda install steps to install a ggd aws cahced reicpe. The
intsallation will skip the sat solver step, ignore packages that may be additionaly installed
or uninstalled, and performs other steps in order to install the data package without using
the sat solver.
The majority of the work is still done by conda through the use of the conda module. This method
should only be used when a cached recipe is being installed.
Parameters:
-----------
#1) pkg_name: The name of the ggd package to install. (Example: hg19-gaps)
1) pkg_names: A list of the names of the ggd packages to install. (Example: [hg19-gaps])
