app.getAppMetrics() and ProcessMetric - memory no longer available

[jarrodek]

• Output of node_modules/.bin/electron --version: v4.0.0
• Operating System (Platform and Version): Ubuntu 18.04.1 LTS
• Output of node_modules/.bin/electron --version on last known working Electron version (if applicable): 3.x

Expected Behavior
The ProcessMetric contains memory entry.

Actual behavior
memory information is no longer available.

To Reproduce

let metrics = app.getAppMetrics();
console.log(metrics[0].memory);

Additional Information
I am using app.getAppMetrics() during development to check memory and CPU usage of my app. I have a task manager view as the one available in Chrome. After updated electron to v4 today I noticed that the memory property is no longer available. I saw other issues related to this: #13385, #13414, and #13383 but it's not clear whether you wanted to remove this metric or find the other way to present this information.
Will memory info be available?

@jarrodek That property was deprecated in 3.0 and removed in 4.0. The appropriate runtime warnings were giving in 3.x releases and it was mentioned in our breaking changes document.

This was an intended API removal as a result of a Chromium API change

[jarrodek]

Are there any plans to introduce new API to get memory info? Just curious. :)
