Add support for trove incremental backups

Added extra column to backups tables (under instances
and under backups) that will show Yes / No if the
backup is incremental (ie it has a parent)

When you drill down into backup details we now display
the name of the backup parent if this is an
incremental backup. This is displayed as a link with
the backup name so it is navigable

When you create a new backup you can now specify
an existing backup to use as the parent

Note: At some point we should probably have the
create backup dialog filter the available parents
based on the current selection for the instance.
However, so far I haven't worked out how to make
the backup parent choiceField change dynamically
based on user updates to the instance choiceField

User signup/signin in newly designed jio-dashboard

Port to master the new user signup, change password, phone number, email
addressed in below blueprints in havana_jio_dashboard branch:
https://blueprints.launchpad.net/jio/+spec/user-registration
https://blueprints.launchpad.net/jio/+spec/change-password
https://blueprints.launchpad.net/jio/+spec/change-phone-number
https://blueprints.launchpad.net/jio/+spec/change-email

P.S.
* The change-* functionalities were implemented using customization modules
in havana_jio_dashboard w.r.t the below URL:
http://docs.openstack.org/developer/horizon/topics/customizing.html
Now, they are implemented as plugins w.r.t the below upstream blueprint
https://blueprints.launchpad.net/horizon/+spec/plugin-panel-config

* User registration feature related URLs loading is slightly modified to avoid
modifications to openstack_dashboard.urls.py file. Instead, a new file
horizon_jiocloud/root_urls.py is added. So, for those urls to work,
add below entry in local_settings.py file
ROOT_URLCONF='horizon_jiocloud.root_urls'

The intention is to avoid as much changes as possible to core files in master
so that rebasing with upstream master is less painful.

N.B.
* Instance count is a required field in UI. So, it can't be simply removed through jquery. So, its first set as 'required=False' and then removed during form init in '_init_instance_name' method and a default value is set in '_init_instance_count' method as its a mandatory field.
* RJIL settings are appended to local_settings.py.example based on the UI team discussion. Refer blueprint for more details
