Disable Server Timing via filter

[tillkruss]

Feature Description

Object Cache Pro and Redis Object Cache both allow users to enable and disable the Redis cache via CLI and UI.

This plugin hijacking the object-cache.php file prevents that core functionality.

I’d like to disable the Server Timing hijack using a filter, not a constant, from my plugins.

It created an unnecessary support burden over the past weeks.

My fairly new object cache plugin, modeled on Till's, has this FAQ https://wordpress.org/plugins/sqlite-object-cache/#can%20i%20use%20this%20with%20the%20performance%20lab%20plugin%3F

At drop-in load time, ordinary plugins haven't had a chance to register hooks.

With respect, I think this approach of borrowing the drop-in is not workable for widespread production.
