Feature request: add a configuration or setting for dev in dependencies, status and snapshot

[jabenninghoff]

With #1636, dependencies, status and snapshot all support a dev parameter that supports inclusion of development dependencies. I love this new feature!

Would you consider adding (or accepting a pull request) a configuration or setting that sets the default value for the dev parameter across all three functions (as TRUE or FALSE)? This would be handy for ensuring consistent behavior.

This seems like it would fit in settings.

Thanks!

After doing some additional research, this feature probably only makes sense for status and snapshot; adding a setting that changes the behavior of these two functions to pre-1.0.0.

Also, such a setting seems needed to suppress the following message at start when using renv::snapshot(dev = TRUE):

- The project is out-of-sync -- use `renv::status()` for details.

This seems like a good idea to me. It also makes sense since renv::status() might get confused if it saw a lockfile created with renv::snapshot(dev = TRUE).
