This patch takes all the HostUtil functionality currently found in mount*.go files and copies it into hostutil*.go files. Care was taken to preserve git history to the fullest extent. As part of doing this, some common functionality was moved into mount_helper files in preperation for HostUtils to stay in k/k and Mount to move out. THe tests for each relevant function were moved to test files to match the appropriate location.
