Indicate status of Zoom meeting on issue
### Problem to solve
It would be helpful context to users reviewing an incident to understand if the indicated conference call is on-going or ended so that...
* I have more context and don't waste time clicking around
* I know if people are actively collaborating on the issue
* I know to remove the zoom meeting if it has ended (this depends on the ultimate design)
<!-- What problem do we solve? -->

### Further details
This work supports the [Incident Management vision](https://about.gitlab.com/direction/monitor/debugging_and_health/incident_management/).
<!-- Include use cases, benefits, and/or goals (contributes to our vision?) -->
### Proposals
Surface an informative button at the top of the issue underneath the title that displays:
* Duration of call - if it is active, can we increment the time in real-time?
* Number of participants in the call
When the call ends, automatically remove the button from the issue.
### Proposed design (TBC)
We surface the additional information as part of the zoom button:

### How will we measure success?
Number of unique interactions with the Zoom button and retention of use
