Cannot customize SITE_BRANDING, SITE_BRANDING_LINK and help_url

[Nobuto Murata]

As per the following document, Horizon allows some customization such as HTML title(SITE_BRANDING), Logo link(SITE_BRANDING_LINK), and Help URL(HORIZON_CONFIG["help_url"]) through local_settings.py.

However, the charm doesn't allow to do so at the moment.

There is a hack available to put local_setting.py under the custom theme directory and upload it as a Juju resource:
https://github.com/openstack/charm-openstack-dashboard#custom-theme

However, the settings there are per theme basis so an ability to put those values to the global local_settings.py is necessary to apply the values for all themes.
