Internal Event Tracking: Add instrumentation to track usage of Fleet Dashboard for Groups

Scope

Add instrumentation to track usage of the Fleet Dashboard at the Group level.

Steps

• Define an event
• Define one or more metrics
• Trigger the event

Metric Requirements

These requirements should match what we implemented at the Admin level Fleet dashboard. We should open additional issues if we need to make them more consistent.

• Count of unique users that selects the Fleet Dashboard.
• Count of unique users that select the export as CSV button.
• Count of unique users that select the Active runners metric card.
• Count of unique users that select the Wait time to pick up a job metric card.
