Description
How can I measure the time a query spends waiting in the connection pool queue when using the waitForConnections: true option in a connection pool?
I'm looking for to somehow do this:
const [result, meta] = await pool.query("SELECT * FROM ......")
console.lg(meta.queteWait) // if this value if bigger than 0, it means this query waited for a connection before being executed in mysql server.

Research direction
No source file or test is named. Start by tracing pool.query with waitForConnections enabled through the connection-pool entry points, then determine where queue-wait timing could be exposed and how it should be verified; done means callers can reliably measure time spent waiting before execution.
