It was only 'sha1' algorithm being used till now in ``hash_file`` method to create hash of the file contents. Need to add 'md5' to keep the consistency with that of IPA code base. Also, this method now supports all the algorithms hashlib does. As this method wasn't being used at all, therefore making the default algorithm to 'md5'. Will be used in oob firmware update (manual clean step) to verify the checksum of the images. Change-Id: I8159fd64d1c074bd539817a40900e34f8fae30d4
