 <#
 To make this a bit less "hard coded", Some changes I want to make:

 1. Pass in a list of files to be copied over
 2. Move $cred as an optional parameter 
 3. pass in $serverHostAction as a param [make it smart enough to handle script blocks vs local path file]
       former just gets executed directly much like what this does 
       the latter would involve copying the file onto the box and then would run a separate invoke action against it
 4. Figure out a better means to generate a final report [html doc]?
       
 The overall workflow is sort of where I want it which is
 1. Copy the local files over via "copy-item -ToSession", but they get copied to a temp folder
 2. Handle configuring $serverHostAction [as called out]
 3. Execute the $serverHostAction
 4. Clean up- remove the temp folder
