Ability to display deprecation notices or other general information on a tool

[natefoo]

From a discussion on wg-ui-ux:

@natefoo Over on .org we'd like to deprecate some tools (e.g. Trinity) while not hiding them, but discouraging their use. We can of course add tags, but it'd be great if we could display some text at the top of them pointing them at alternatives and maybe some trainings that use other tools.

@wm75 suggested using help forum integration (#16798), which seems like a great idea, although these appear at the bottom of the form, rather than the top. We could curate what would be found and displayed by using tags:

@wm75 Currently you can't, but the whole discovery process is controlled via tags anyway, so shouldn't be hard to add a few more for setting priority.
and maybe the tool interface could, at the top, alert users if a tool has high-priority help available?

As Wolfgang points out, one nice benefit of using the help forum integration is that this would benefit more than just a single instance.

I'm opening a discussion for two reasons:

1. Does this seem like a good or bad idea? Any other ideas? and,
2. How should this work on the tool form, if we want to display something more prominently?

A few things that we are currently discussing are:

• failing jobs with an appropriate error message, e.g. you can use blastp on tiny files, but we will bail out on large files and recommend diamond blastp to our users
• using the new notification system after the fact ... e.g. sending notifications like "we have seen you have been using tool X on Y, but we recommend you to use Z instead because its ..."
• use more features of the tool recommendation system in Galaxy ... tweaking recommendations to nudge people into more recent tools

Two tools where we can try Wolfgangs approach easily and maybe others is prokka/bakta and tophat, for both we know that the upstream developers recommend other tools nowadays.
