allowed_query_strings_urls for full measure static caching

[stuartcusackie]

I just realised that the allowed_disallowed_query_strings options have no effect with full measure static caching. It presents a problem for me as my site needs to ignore gtm_ referal queries but allow collection pagination queries. I don't understand the technicalities of why these options don't work with nginx, but I wonder if there is a workaround.

In reality I'm never going to be using a Google campaign to link to a paginated url, i.e. it makes no sense for my Google ads to link to mywebsite.com/?page=2. So if the these options will never work for full-measure static caching then I wonder if there could be a new option in the static caching config called allowed_query_strings_urls.

`ignore_query_strings' => true,
'allowed_query_strings_urls' => [
  '/blog'
]

This way GTM query strings would be ignored on all pages, except for the '/blog' page, where I need pagination.

Is this possible or am I missing something? Thanks!

Also, it would be nice to have an additional comment in config/static_caching.php to remind us that the current options are incompatible with full measure.
