Ceilometer configuration.rst file not using right param names for logging
Ceilometer configuration.rst file not using right param names for logging

configuration.rst file lists all the configuration parameters for ceilometer
configuration. However, for logging, these parameter names should be log_dir
and log_file, but currently it is logdir and logfile.

The table also misses log_config.

There should be a link in configuration.rst file to point a user to the
sample configuration file.
