of the pooling code that existed in snf-common ('synnefo.lib.pool')

Loggers for all synnefo components should be configured in
snf-webproject setting file '10-snf-webproject-logging.conf'.

Do not automatically update version files

Do not automatically update version files from setup.py. From now
on, version files are updated using 'update_version.py' script and
'devflow'.

Also removed autopkg.conf and created devflow.conf configuration file.

Pool pithos backends using ObjectPool

Use ObjectPool functionality from synnefo.lib.pool
to pool backend objects.

This reduces the per-request overhead significantly,
since each backend object is only initialized once,
and connections to the DB are persistent....

Updated snf-webproject hooks

Updated snf-pithos-app dependencies

added south package

Handle synnefo imports in setup.py files
