feat: add global options deprecation warnings

BREAKING CHANGE:

As part of ac31f01 global options which are only relevant to some commands have been moved to those specific commands.

This left some users confused, because this was done without warning or major version change. This change seeks to remedy this, by adding deprecation warnings as well as triggering a major version bump.
