Hide column on multi_select tables if no actions available.

This patch will add a runtime check to hide/show checkbox columns
on multi_select tables.
Right know the behaviour is calculated once but does not take in account
the dynamic allowed call of each Table Action available.

The change will add 'hidden' class to the first column if table actions
are present but all of them returned False on allowed() call.

Add missing mock for cinder.default_quota_get

When running tests, I get the following logs:

INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1):
public.nova.example.com

DEBUG:cinderclient.client:Connection refused:
HTTPConnectionPool(host='public.nova.example.com', port=8776): Max retries
exceeded with url: /v1/os-quota-sets/1/defaults (Caused by <class
'socket.gaierror'>: [Errno -2] Name or service not known)

Which signify, that there is a mock missing in the tests.
This patch adds that missing mock.

Cardinal interpolation error

-Seems like for the big numbers, d3 is interpolating
 data badly and it is creating loops in the chart.
 So quick fix is to switch to linear interpolation
 as default.
-Other interpolation can be set with settings.

Fix documentation about adding a new dashboard

Since blueprint plugin-architecture has been implemented,
the preferred way to add a new dashboard is a configuration
file, rather than an entry in INSTALLED_APPS.

This patch changes the developer documentation to reflect
this change.

Improve Host Aggregates handle method.

Added update conditions to the handle method (remove
and add hosts).
Previously, to perform an update, first all existing hosts
were removed and then all new hosts were added.
Now, the update method only
remove or add the changed hosts.
Added missing unit tests for the update.
