  - Merge "Reduce memory consumption in Cinder services"
  - Reduce memory consumption in Cinder services
    
    This patch reduces memory usage on the Cinder Volume and Backup services
    by tuning glibc.
    
    The specific tuning consist on disabling the per thread arenas and
    disabling dynamic thresholds.
    
    The Cinder Backup service suffers from high water mark memory usage and
    uses excessive memory.  As an example just after 10 restore operations
    the service uses almost 1GB of RAM and does not ever free it afterwards.
    With this patch the memory consumption of the service is reduced down to
    almost 130MB.  If we add a revert from Cinder (Change-Id
    I43a20c8687f12bc52b014611cc6977c4c3ca212c) it goes down to 100MB during
    my tests.
    
    This glibc tuning is not applied to all Python services because I
    haven't done proper testings on them and at first glance they don't seem
    to have such great improvements.
