Subject: [PATCH] Allow for manual setting of default service region in config

In case DEFAULT_SERVICE_REGIONS setting in Horizon config is specified
(on a per-endpoint basis), use it instead of a value stored in
cookies. This value is still checked for sanity, i.e. it should be
present in Keystone service catalog.
