Host Template - Upload

Host template is staged, parsed and checked for conflicts to see if an import would be successful.

}

Returns for a success:

{
 success: true,
 stdout: ['text from opspack','next line'], // Strings from the opspack test import process
 exists: true,                   // Returns true if there is any conflict in the opspack for importing. Details in the stdout
}
