This is mostly deprecation fixes and blueprint changes. There
are some dependency updates too; the changes to Ember
Basic Dropdown necessitated changing it to angle bracket
component invocation. The conversion of the rest of the
templates will happen separately.
The UI will no longer try to redirect to the appropriate namespace or
region if one is found in localStorage. Instead, it will assume that
the lack of query param means the default namespaces or region is
desired.
