Gauvain Pocentek 4fa84ee7c5 Use CEILOMETER_TOKEN instead of ADMIN_TOKEN for ceilometer secret key
The ADMIN_TOKEN replaceable is already used to reference the keystone
secret token, using it again for ceilometer might confuse readers. Using
CEILOMETER_TOKEN should make things clearer.

<title>Install the Compute agent for the Telemetry service</title>
