Add missing Keystone options to registration of config

This patchset adds missing Keystone options to registration
of config, including timeout.

This fix is similar to a recent Shipyard patchset [0] which
aimed to solve the same issue but expands on it by following
Nova patterns here: [1].

This also updates the sample config file which now includes
the timeout option.
