Adrian Turjak 88fb018840 Rework DEFAULT_SERVICE_REGIONS
DEFAULT_SERVICE_REGIONS is cumbersome when you have
more than one keystone endpoint and all you want to do
is set a global default service region.

This adds '*' as an optional fallback key to mean global default.
If an endpoint matches it will take precedence over the '*' value.

This also fixes the precedence order for DEFAULT_SERVICE_REGIONS
so that a user controlled cookie is used instead when that cookie
is valid for the given catalog. This changes the way the setting
works, but retains the intended result the setting was originally
intended for.

DEFAULT_SERVICE_REGIONS can now take '*' as a key which serves either as a
fallback service region, or the default region if no other keys are set.

[:bug:`1772345`]
``DEFAULT_SERVICE_REGIONS`` no longer overrides the cookie value from
``services_region``. This fixes the UX where a user controlled value
keeps being overridden by a setting and changes ``DEFAULT_SERVICE_REGIONS``
to act as a default (as the name implies) per endpoint if the cookie is not
set rather than an override. The cookie will still be overridden when
it is for a region not present in the user's current catalog, so this will
still handle the original multi-keystone case that requried the
introduction of ``DEFAULT_SERVICE_REGIONS``.
