Implement "client" pattern for storage #952
Description
Taking #910 as a template, this is my proposed order of work:
- Adding client class side-by-side existing (Adding basic client class in storage. #964) (
likely will factor out the pubsub client in)corefirst, see Adding base client class in core. #953 -
Adding factory constructors to client.(Done by the parent class in Adding base client class in core. #953) - Move methods from
storage.apionto the client and removeapimodule (Remove storage.api module and move methods onto client #973) - Replace client in places where a connection is used (Replace optional connection with client in storage methods and functions. #984, Replace connection in bucket constructor. #987< 7D06 /span>)
- Drop the
_implicit_environmodule - Update regression tests (may just do this progressively over several PRs instead of a brain dump PR like Attempt at implementing clients for Pub/Sub #910 was)
- Update docs (ditto here)
