Warn OPENSTACK_QUANTUM_NETWORK setting as deprecated

Change-Id: If2f762fe665b9a88153a77a658f52bcd56185c53
Closes-Bug: #1377498
(cherry picked from commit 530e5fee789ce5ed19d90a6b4901f01e8efde5ff)
Document token hash algorithm option

With https://review.openstack.org/#/c/116509/ ,
django-openstack-auth will support a new option for the token hash
algorithm. This adds the documentation to Horizon's local settings
example file.

This is for security hardening. The token hash algorithm defaults
to MD5, which is considered too weak due to the potential for hash
collisions. Some security standards require a SHA2 hash algorithm to
be used.
