Remove trailing slash from ceilometer endpoint URLs

Fixes bug 1146794

Ensure the URLs configured for the ceilometer endpoint in the keystone
service catalog do not contain a trailing forward slash.

Otherwise, this leads to an extra forward slash in the URL paths
constructed by the ceilometer client, which in turn is problematic
for the v2 API.
