Service URL and API URL where set the other way around.
Also add checks for the URLs being in use.

Service name is significant: UI presentational data are indexed by
it; resource names are prefixed by it.

Update /servers API, to include attachments to /servers responses,
even if the server has no NICs.

Raise a BadRequest if request is missing Content-Type header field.

Following Keystone there is now a `type' field in model Service.
This adds a data migration in order to set the type for existing
services as follows:
  astakos:  identity
  cyclades: compute
  pithos:   storage

Leave the most important fields of Service in service-list;
show all fields with service-show.

We do not support removing a registered service or resource.

Unset execute bit for file service-add.py

Do not fail when looking up the unit, if resource is not found.

Replace ASTAKOS_SERVICES and ASTAKOS_RESOURCES_PRESENTATION_DATA with
ASTAKOS_SERVICES_META and ASTAKOS_RESOURCES_META in conf files
respectively.

There is no need for a qh node since the integration in astakos.

Remove remaining astakos and pithos-related references of quotaholder
from settings and docs.

Export astakos api urls as global variables that can be
easily changed, rather than hard coded values.

All user-related API calls make use of this decorator to authenticate
the user. Previously it used to check only for the existence of the token;
now it makes all checks previously found in the `authenticate' API call.
The latter now just prepares the response data; it depends on the
decorator for authentication per se.

It is view-specific and did not deserve a separate file.

Since v0.14 everything belonging in a README file should be written
as part of the documentation and thus under docs/. Remove all
unnecessary README files, adjust MANIFEST.in and setup.py files
accordingly and move README files that should be merged into the
documentation under docs/older/.

This will be followed by a commit that merges all necessary
information included in the remaining REAMDE files under docs/older/
in the corresponding guides and docs, so that everything is up-to-date.

Use 'parse_bool' function to parse '--dhcp' option. Also, include
'dhcp' to default columnds of 'network-list' command.

Since 0.13 there is only one single Changelog file at the root
directory. Thus, any new component should not have its own
Changelog file. Specifically, remove local Changelog files for:

* snf-astakosclient
* snf-branding
* snf-django-lib

Add library synnefo.util.units for parsing numerical values
with an optional unit suffix and printing integer values based
on a given style.

Styles `b', `kb', `mb', etc allow printing in the respective multiples
of byte, style `auto' in a human-readable manner, while `none' omits
units altogether.

Add option `--unit-style' in all astakos management commands that print
resource limits and quota usage. Consult the resource definitions to find
out which unit, if any, to show. For resources with unit `bytes', all
commands default to MB.

get_menu is used only by astakos cloudbar:
it should not be under astakos api services

Import astakos settings module instead of importing specific settings

The synnefo developer is urged to create a directory,  place inside all the 
the email .txt files he/she wishes to overwrite (respecting the indicated 
structure) and provide the directory path to theTEMPLATE_DIRS setting.
