Description of problem:
OpenStack keystone needs the following policy:

#============= keystone_t ==============
allow keystone_t self:process signal;

or else will throw an Error on startup. Certain LDAP-related functionality does not work without that policy too.

Version-Release number of selected component (if applicable):
Name        : openstack-selinux
Version     : 0.5.19
Release     : 2.el7ost
From repo   : openstack-juno

Name        : openstack-keystone
Version     : 2014.2.2
Release     : 1.el7
From repo   : openstack-juno

How reproducible:
Start openstack-keystone

Actual results:
/var/log/keystone/keystone.log will contain:
