Replace deprecated "decodestring"

decodestring() is a deprecated alias, use decodebytes()
https://docs.python.org/3.1/library/base64.html#base64.decodestring

This patch helps to remove this deprecation alias by
replacing "base64.decodestring" with "oslo_serialization.base64.decode_as_bytes".
The same has been done for nova:
