Hi All,

Problem description:

Monty Taylor added split-logger functionality in patch[1].
This functionality splits logs in four different logs:

*         keystoneauth.session.request

*         keystoneauth.session.response

*         keystoneauth.session.body

*         keystoneauth.session.request-id

Working on enabling this split_logger functionality for cinder to its internal 
clients interaction (like glanceclient, keystoneclient, novaclient).

Steps followed to enable this functionality:

1. Register the configuration option 'split_loggers' in keystoneauth [2].

2. After registering 'split_loggers' option in keystoneauth for cinder to 
novaclient interaction, need to set value of 'split_loggers=True/False' under 
[nova] section of cinder.conf, so that this 'split_loggers' value will get 
loaded from [nova] section at the time of loading session [3].

So trying same approach for cinder to glanceclient interaction, but there is 
one difference:
                glanceclient uses 'load_from_options' method [4] while loading 
                And novaclient is using 'load_session_from_conf_options' 
method[3] from keystoneauth.


For this need to register the session conf options from keystoneauth under 
[glance] section which earlier was under [default] section.
Please refer changes made for this[5].

Pros of using this approach:

1.       As we are setting conf option in keystoneauth it will directly load 
value of 'split_loggers' from conf file.
So no need to pass explicitly 'split_loggers' value at the time of loading 
keystoneauth session.

Cons of using this approch:

1.       Need to register session conf options under [glance] section instead 
of [default].

Need opinion on this as it is changing the group from [default] to [glance] for 
session conf options.
