Pls add appropriate OSs label.

It's a blink change, but more applicable to Android, and so set the OSs label as "Android".

Your change meets the bar and is auto-approved for M58. Please go ahead and merge the CL to branch 3029 manually. Please contact milestone owner if you have questions.

commit e66f2ff1ce2c15bb342ad8dd7579a0578af1d6bc
Author: binlu <binlu@google.com>
Date: Mon Apr 24 21:19:57 2017

Remove vibrate w/o user gesture by default.

Change the flag from "experimental" to "stable" and from 'DISABLED_BY_DEFAULT' TO 'ENABLED_BY_DEFAULT': Calls to navigator.vibrate will return 'false' if user hasn't tapped on the frame or any embedded frame yet.

This is for M60 since M59 had branched last week, and the previous CL has been merged to M59:

This issue has been automatically relabelled type=task because type=launch-owp issues are now officially deprecated. The deprecation is because they were creating confusion about how to get launch approvals, which should be instead done via type=launch issues.

We recommend this issue be used for implementation tracking (for public visibility), but if you already have an issue for that, you may mark this as duplicate.

Remove the browser feature for VibrateWithoutUserGesture

The renderer feature was removed in https://crrev.com/86dad9f3, except
for the linkage between browser and renderer in c/c/runtime_features.cc.
This CL removes that link, as well as the base::Feature for the removed
feature, and the entry in chrome://flags.
