remove keystonemiddleware settings from api-paste.ini

They can/should be set in the trove.conf instead, to
centralize all user-preserved/editable changes in the main
configuration file, and allow the ability to track api-paste.ini
unmodified from master.

Obsolete oslo-incubator modules - jsonutils (now oslo.serialization)

This change is part of a multi-part change set to handle obsolete and
graduated oslo modules. This commit handles the jsonutils module which
is now oslo.serialization.jsonutils. The change here is to remove it
from openstack-common.conf and point all people who used to use that
at oslo.serialization. requirements.txt has been updated to point to
this dependency.

The file jsonutils.py is not being deleted because of dependencies in
oslo-incubator.

Change has been rebased on https://review.openstack.org/#/c/129294/
