Allow customization_module option to be set and managed in horizon config

[Lokesh Jain]

Horizon has a global override mechanism available to perform customizations. This adds a key - customization_module - to HORIZON_CONFIG dictionary in local_settings.py. Currently there is no way to either set this value or expose it for configuration. This option needs to be added and exposed for users to configure. The value should be a string with the to the module containing modifications in dotted python path notation. The parameter should default to undef

Example:
customization_module => "my_project.overrides"
