ls/import/get: introduce --remote and --remote-config

[efiop]

Similar to how it is used in api. --remote is used to specify a new default remote to set, while --remote-config can amend that (or just old default if --remote not specified). Example:

dvc get URL path --remote-config "access_key_id=mykey" "secret_access_key=mysecretkey"

Fixes #9656

Docs will be in treeverse/dvc.org#4722
