ModuleNotFoundError: No module named 'six'

[mosneji]

Describe your environment.
Python 3.10
opencensus==0.11.2

Steps to reproduce.
pip install opencensus==0.11.2
and try to do: from opencensus.common.schedule import Queue, QueueEvent, QueueExitEvent

What is the expected behavior?
Modules get imported

What is the actual behavior?
Error message: "ModuleNotFoundError: No module named 'six'"

Additional context.
"opencensus" is using "six" and "google-api-core"
"google-api-core" is using "google-auth"
"google-auth" is using "six" in the versions previous to "2.23.0" (it was released 2 days ago)
So now if we try to do pip install opencensus==0.11.2, google-auth-2.23.0 will get installed and "six" won't which would break "opencensus"

I guess "opencensus" should add "six" as a dependency as it is being used in its source code.
