Some HTTP requests fail if "uri"type is "bytes"

[zoosmand]

File "/snap/google-cloud-sdk/current/lib/third_party/httplib2/python3/httplib2/init.py", line 1776, in request
uri = uri.replace(" ", "%20").replace("\r", "%0D").replace("\n", "%0A")
TypeError: a bytes-like object is required, not 'str'

Particularly, "google-cloud-sdk" using your lib, passes bytes in some occurrences.

This could be simply be fixed like this (nearby the line 1533):

if isinstance(uri, bytes):
    uri = uri.decode("utf-8")

just before uri = uri.replace.....
