remove $KEYSTONE_TOKEN_HASH_ALGORITHM

Now that Keystone is back to UUID token defaults the use case for this
in devstack is extremely dubious, and it can be set through via
local.conf if anyone *really* cares.

Add WSGIPassAuthorization to the admin port too

Accidentally only added WSGIPassAuthorization to the public port,
like all the other WSGI props, it should be added for both ports.

Fix rabbit_userid for multi node devstack

I43a231c9611b4cc2e390b603aa3bfb49c915bdc5 introduced a new setting
RABBIT_USERID but only set it if rabbit is enabled. In multi node
devstack the second node uses RABBIT_USERID but the service rabbit isn't
enabled on it.

Always set RABBIT_USERID, if a different message queue is used the
variable will just be ignored.

Don't install sphinx from distro

We don't generate docs in devstack. But also, sphinx depends on babel
which has a hard depend that breaks with setuptools 8. However, pip
installed babel/sphinx should not have this problem.

now.
