Missing references in FrameworkBundle Configuration doc

[maidmaid]

Working on symfony/symfony#21081, I found a few missing references in FrameworkBundle Configuration ("framework") documentation. It's:

• framework.profiler.matcher.ips -> this option was removed: https://symfony.com/doc/4.0/profiler/matchers.html
• framework.workflow.* -> Bootstraped the documentation of Workflow options #11041
• framework.session.use_cookies -> Documented the missing session.use_cookies config option #11039
• framework.session.metadata_update_threshold -> https://symfony.com/doc/current/reference/configuration/framework.html#metadata-update-threshold
• framework.request.* -> https://symfony.com/doc/current/reference/configuration/framework.html#request
• framework.validation.static_method -> Documented the missing validation.static_method option #11040
• framework.property_info -> https://symfony.com/doc/current/reference/configuration/framework.html#property-info
• framework.cache.* -> https://symfony.com/doc/current/reference/configuration/framework.html#reference-cache

I'm closing this as fixed 🎉 because everything has been documented or there are open pull requests for adding the docs. Thanks for reporting this.
