Horizon: package improvement

[Thomas Goirand]

This is a general review of the package.

- Unit tests not done at all at build time.
- Package is running "collectstatic" which isn't useful, and even potentially dangerous. Instead, everything should simply be using the xstatic packages.

debian/pydist-overrides
-----------------------
- This file should really contain equivalent packages, not just remove dependencies.

debian/copyright:
-----------------
- Missing entries for debian/* files
- Missing entries for debian/static/* files

debian/changelog:
-----------------
- Missing past Ubuntu entries

General issues:
---------------
- No compile of gettext messages: no translation therefore?

- Dangerous deletion of UID / GID on purge

- Package contains already compiled javascripts in debian/static/openstack-dashboard/js/*. This is dangerous in case of security problems with .js thirdparty libs, and that's also almost certainly a license violation. I can see code from the d3 lib for example.

debian/control:
---------------
- Why build-depends on nose and others if unit tests aren't even run?
- Useless Depends: python-lockfile

[Ivan Udovichenko (iudovichenko)]

Switched to Debian source packages which already has provided changes.
