Planned removal of `report_todo`

[calebcartwright]

The purpose of this issue is to both communicate our intent to drop the unstable option report_todo, as well as provide a forum for questions to be asked and/or concerns to be raised.

We do not yet have an exact deprecation date planned, but it will most likely occur in early 2022.

While we understand the utility this option provides, we've decided that rustfmt simply is not the right place/tool to provide this capability, and it's not an option that makes sense for us to try to stabilize and maintain/support long term.

If anyone is aware of any other community maintained tools/crates for detecting "TODO" strings in comments please feel free to post here for broader awareness.

Just for clarity, and because report_todo and report_fixme are practicality synonymous to many people, is just report_todo being depreciated? Tx

Thanks for the question, and yes report_fixme is being deprecated as well - #5102
