Add unit tests to verify the precedence of access_log_ and log_
prefixes to options.
Add pointers from proxy_logging sections in other sample config files
to the proxy-server.conf-sample file.

The internal client is suppose to be internal to the cluster, and as
such we rely on it to not remove any headers we decide to send. However
if the allow_modify_pipeline option is set the gatekeeper middleware is
added to the internal client's proxy pipeline.
So firstly, this patch removes the allow_modify_pipeline option from the
internal client constructor. And when calling loadapp
allow_modify_pipeline is always passed with a False.
Further, an op could directly put the gatekeeper middleware into the
internal client config. The internal client constructor will now check
the pipeline and raise a ValueError if one has been placed in the
pipeline.
To do this, there is now a check_gatekeeper_loaded staticmethod that will
walk the pipeline which called from the InternalClient.__init__ method.
Enabling this walking through the pipeline, we are now stashing the wsgi
pipeline in each filter so that we don't have to rely on 'app' naming
conventions to iterate the pipeline.

Modify the 'log_name' option in the InternalClient wsgi config for the
following services: container-sharder, container-reconciler,
container-deleter, container-sync and object-expirer.
Previously the 'log_name' value for all internal client instances
sharing a single internal-client.conf file took the value configured
in the conf file, or would default to 'swift'. This resulted in no
distinction between logs from each internal client, and no association
with the service using a particular internal client.
With this change the 'log_name' value will typically be <log_route>-ic
where <log_route> is the service's conf file section name. For
example, 'container-sharder-ic'.
Note: any 'log_name' value configured in an internal client conf file
will now be ignored for these services unless the option key is
preceded by 'set'.
Note: by default, the logger's StatdsClient uses the log_name as its
tail_prefix when composing metrics' names. However, the proxy-logging
middleware overrides the tail_prefix with the hard-coded value
'proxy-server'. This change to log_name therefore does not change the
statsd metric names emitted by the internal client's proxy-logging.
This patch does not change the logging of the services themselves,
just their internal clients.

Multiple files and documents showed that log_statsd_host had
a default value, usually localhost. This was incorrect, instead
setting a value for log_statsd_host enables statsd logging.
Removed any reference of log_statsd_host having a default value.
Also changed descriptions to show setting a value enables logging.

This patch changes container sync to use Internal Client instead
of Direct Client.
In the current design, container sync uses direct_get_object to
get the newest source object(which talks to storage node directly).
This works fine for replication storage policies however in
erasure coding policies, direct_get_object would only return part
of the object(it's encoded as several pieces). Using Internal
Client can get the original object in EC case.
Note that for the container sync put/delete part, it's working in
EC since it's using Simple Client.
