Internal Page Cache does not "vary" for Anonymous users in 9.x, 10.0 and 10.1. IP embargoes needed that. Kill cache

What?
Basically anonymous users have no Cache Context. They do not vary. So IP embargoes only work for Logged in users in a reliable way right now. Solution?
1.- Check if embargoes are enabled at all
2.- Check if user is anonymous
3.- If anonymous, check if IP data (for allowing/not allowing) is at all present in the ADO
4.- If present, check if the Internal Page Cache module is enabled (if not, the smart cache, which is aware but also slower, can deal with it, treating anonymous as a varying user) and Kill the Page Cache.
5.- Set any output after to max-age = 0 to ensure there is not even client level caching
This needs to be applied at a single point (good!) because we have a cache resolving service (good Diego)
@alliomeria for tomorrow
I will also make a backwards compatible one for 1.2.0 soon
