Plugin-based dashboard configuration

This is a proof of concept of how plugin-based configuration of
OpenStack dashboards could be realized. Additional plugins add
their configuration file in the opestack_dashboard/enabled/
directory (the exact location is up for discussion, we will
probably want a whole hierarchy of locations, with the possibility
of overriding settings).

An example file _50_tuskar.py is added to show how an additional
dashboard could plug into this system. If you have tuskar_ui installed,
this would add Tuskar to Horizon.

Set can_set_mount_point default to False

Patch https://review.openstack.org/#/c/59229/ only changed the default
value in the local_settings.py example file. If the setting isn't defined,
it still defaults to True

Removal of json2.js

    As long as Horizon does not support any browser lower than IE8,
json2.js library is no longer needed, browsers have a native
implementation of JSON.stringify and JSON.parse.
    Removing this script allow us to reduce the javascript footprint
of Horizon.
    jQuery $.parseJSON will replace all parsing of JSON in order to
standardize the use of this functionnality.

CSV Summary not working inside Admin panel.

When browsing Project usages from 'Admin->Projects->More->View Usages'
an AttributeError exception is thrown due to missing csv_render_class
attribute.
Also, project_id instead of tenant_id in BaseUsage  were expected, so
any request to /admin/projects/[id]/usage/ will always return the current
tenant from session.
This fix reuse logic from project/overview/ into this view.

Hide key field in edit Flavor Extra Specs dialog

Add architecture field in image properties.

It would be beneficial for us to be able to add architecture
to the image file, and we already have an architecture field
on update Image dialog.

Fix URLs of panels grouped into packages

If you group related panels into packages using the
dot notation, the URLs generated for them will have
the dot in them where you would rather expect a
slash. This patch fixes it by replacing the dots in
the panel slug with slashes when generating URLs for
them.

Specify tenant_id when retrieving LBaaS/VPNaaS resource

In Neutron API, resources from all tenants are listed when
retrieving a list of resources with admin role. Horizon
project dashboard is for project-specific operations,
so we should retrieve only resources of the given project.
LBaaS/VPNaaS panels have this problem, but FWaaS does not.
router_list should be called with tenant_id filter too.

This commit also fixes VPN/FWaaS tests so that it extract tenant_id
from request attribute rather than use tenant_id of test_data.
