Add metadata option to Nova Create API Wrapper

The Nova Create API Wrapper doesn't pass through
the metadata variable, requring any dashboards
that spin up VMs with metadata to use the python
libraries directly.

Closes-Bug: 1347824

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.

https://github.com/JioCloud/horizon/commit/7a4864a13635ad334232f60205d33edd278c84b5

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
