Allow for the exclusion of cookies and by prefix to allow for dynamic ranges

[marcrobertscamao]

In many cases specifically related to affiliate links there are dynamic cookies and dynamic query parameters generated in order to support this case I would recommend that it is possible to exclude entire ranges of parameters based on prefix, such as the following range of cookies where <wpid> is set from the partner domain _ga_<wpid>

My suggestion would be to configure prefixes as follows:

Flowpack:
  FullPageCache:
    request:
      cookieParams:
        ignorePrefix:
          - _ga_
      queryParams:
        ignorePrefix:
          - utm_

I will open up a merge request with a first draft so that we can review.
