Add usage ping counters for Quick Actions

Problem To Solve

Quick Actions are used by power users, but they are very simple and if only more people would know them, they would use them (at least that is my hypothesis). Once someone finds out about them -they will feel delight.

Why should we consider them simple instead of a power tool?

Slack has democratized the / commands and therefore I don't consider Quick Actions a power tool that limited audience will use.

We have spent so much energy building these out -- and it is a shame that people don't know about them. Instead of focusing our energy on adding every single item in UX and then dealing with the inevitable response (Too many things in the UI, its cluttered, etc) -- it would be great to make them discoverable.

Proposal

If we want to improve -we need to measure, experiment, measure.

Place a next to each command once MAU counters have been added for each.
