Track user marks and measures on the lhci server dashboard

[rajsite]

Is your feature request related to a problem? Please describe.

I'm capturing User Timing marks and measures in my lighthouse reports and I can see the difference if I compare two runs directly like follows:

But I can't find a way to visualize them on the dashboard:

For these runs the performance score is zero because for these runs I am only interested in the user mark values:

module.exports = {
    ci: {
        collect: {
            settings: {
                onlyAudits: ['user-timings']
            }
        },
    },
};

Describe the solution you'd like

I would like to see the trend in values for my User marks and measures over time on the lhci server dashboard.
