Add option in config/cli to exclude dev-dependencies for the workspace

[Jake-Shadle]

Right now we disregard all dev-dependencies for non-workspace crates as they aren't even actually used in the workspace itself, however it's quite often that dev-dependencies of the workspace pull in eg duplicates or other issues that, while they do affect the workspace, are less of a concern since they are not actually a part of the final binary output of the workspace.
