Create common helper function, for command line tools, to get an object
from DB by it's ID, and raise the appropriate command error if the
object does not exist or the ID is invalid.

Move all management commands from 'api/management/commands' to
'logic/management/commands'.

Look up of ports should check the port userid and not the network
userid.

Create common module for pretty-printing database objects. Currently it
contains only functions for pretty-printing networks and ports.

Add backend code to create and remove ports from Ganeti backends. Also
add some imporovements and fixes to logic, API code and management
commands.

This command will provide info about the port concerning the DB and
the Ganeti state. For now, it provides only DB info.

Make 'server-show' and 'server-inspect' management command to display
the 'task' and 'task_job_id' fields of the vm.

Rename CYCLADES_ASTAKOS_SERVICE_TOKEN to CYCLADES_SERVICE_TOKEN for
uniformity.

|___________________________________| |__________| |________| |_______|
             BASE_HOST                  BASE_PATH    PREFIX    Hardcoded
|_________________________________________________|
             SERVICE_BASE_URL

- Introduce <SERVICE>_BASE_URL setting, and <API>_PREFIX constants
  for all services. Extract BASE_HOST, BASE_PATH from the setting.

- Use settings and constants to construct top-level patterns
  (base-path/api-prefix) in services' urls.py

- Refactor/extend proxy() to be compatible with the above.

- Change URLs passed around (ui, e-mails) to be compatible.
  (needs more work)

Notes:

This configuration REQUIRES that any rewriting and proxying on the
front-end must eventually result in the application server (gunicorn)
getting the original path of the request, otherwise the view-generated
URLs will be different.

Changes:
- set top-level urlpatterns from <SERVICE>_BASE_URL
- rename setting: APP_INSTALL_URL to CYCLADES_BASE_URL
- rename setting: ASTAKOS_URL to ASTAKOS_BASE_URL everywhere
- introduce setting: PITHOS_BASE_URL
- update shipped .confs, quick install admin guide, upgrade guide
- fix urls/views/reverse()/other that were broken
- (more not listed)

Move UserCache from synnefo.management.common to synnefo.lib.astakos.
Also, update ListCommand with 'astakos_url' and 'astakos_token' class
attributes, which must be declared only when 'user_uuid_field' is used.

When the snf-manage {server, network}-list commands are invoked with the
--displayname option, batch the UUID-to-displayname requests to astakos,
instead of issuing a request for each (unique) UUID.
