Rename daemon CLI command to cache (#4808)

* internal/cmd/wrapper: add deprecation wrapper

The deprecation wrapper can be used to display a warning to callers
when a command is deprecated.

* all: rename daemon to cache

Rename the boundary daemon command to boundary cache. This
avoids confusion with future client/daemons.
