Support `dynamic-quota-resources` in nova

Summary
=======
This blueprint is registered to support the proposing feature as soon as "dynamic-quota-resources" would be implemented in nova.
"dynamic-quota-resources" is blueprint in nova.
https://blueprints.launchpad.net/nova/+spec/dynamic-quota-resource

Motivation
========
The quota limits is an important feature for limiting resources in each project.
Currently, Administrator can manage quota values of each project in Projects page
and project user can confirm the values by the pie chart in Overview page.

By supporting "dynamic-quota-resources", the quota items that can manage or confirm are increased.
Since Quota value is the important information that shows how much resource could be used by the project user,
all Quota values should be displayed in horizon.
But, because the number of dynamic quota is indefinite, just increasing the number of displayed items will not
work. It may degrade the readability.

So, we should make a more useful page to manage or confirm the existing quota and dynamic quota.

Description
===========
The following features will be added to horizon:

a) Show the management page of dynamic quota for Administrator.

Administrator will be able to manage the dynamic quota by blueprint in nova.
And, it will be possible to manage even from horizon by supporting the
Features described in the blueprint.

b) Show the reference page of dynamic quota for project user.

Project user will be able to check the dynamic quota by supporting the
feature described in the blueprint of nova.
It will be possible to check it via horizon by supporting the feature.
(The page that can help checking it in a simple way would be supported)
