Add support for keystone_authtoken/memcache_use_advanced_pool

This change introduces a single parameter, MemcacheUseAdvancedPool, to enable usage of advanced connection pool in keystone middleware. This is useful to avoid bursting connection to memcached. Note that the default value of memcached_use_advanced_pool was changed from false to true during Xena cycle[1], so this parameter is no longer required in master. However the change in keystonemiddleware will never be backported. This change is created so that we can switch to advanced pool even in older releases.
