[pradeep910]

Integrate a pagespeed insights library that can give us real results or issues of the page.

It can be done in following steps:

• [ ] Identify the library that can work best for our rt-optimizer plugin. See https://github.com/topics/google-pagespeed-insights

• [ ] Add the library to the rt-optimizer plugin

• [ ] Add a link to the admin bar on frontend something like this, notice rtOptimizer Insights.

• [ ] On rtOptimizer Insights button click, Trigger the pagespeed analysis.

• [ ] Show all the recommendations / results at the bottom of the screen like query monitor does.

• [ ] Automate or apply fixes for the pagespeed recommendations directly using WordPress filters and other means wherever possible.
