refactor(kubernetes/oracle): remove unread kubernetes/settings.ts and…

… oracle defaults (#8321)

* refactor(kubernetes): remove unread settings.ts

Only the legacy (V1) provider read from these settings; they V2 provider does not require a statically supplied
default account or namespace.

* refactor(oracle): remove unused oracle template from halconfig/settings.js

It appears that Halyard's DeckProfileFactory has never actually hydrated any Oracle defaults, so I'm not sure why this was added to Deck.
