FOSHttpCache

• Support Symfony 7
• Drop support for Symfony < 6.4
• Test with PHP 8.2 and 8.3
• Drop support for PHP < 8.1
• Switched to PSR-17 message factories
• Switched some places to PSR-18 HTTP client. The main functionality needs the Httplug Async Client specification. There is no PSR for asynchronous clients.
• Parameter and return type declarations where possible.
• Ignore empty tag lists passed to TagCapable::invalidateTags so you don't need to check if there are tags or not.

• Avoid deprecated RequestMatcher in favor of IpsRequestMatcher.

• Declare incompatibility with Symfony 7 because it removes RequestMatcher.

• Directly require php-http/message-factory to keep working with the legacy factories.

• Provide a TagHeaderParser that can split up a tag header into the list of tags.
  This allows to correctly handle non-default tag separators in all places.

• Fixed varnish configuration examples to say Authorization and not Autorization.

• Fixed dummy interface name for code scanners to match the expected name.

Symfony Compatibility

• Removed the internal BaseEvent class and extend our events from the Symfony contracts class directly.
• Made the CacheInvalidation interface compatible with Symfony 6.
  Symfony 6 does a BC break for HttpKernelInterface::fetch - if you implement the method in your application,
  you need to adjust when upgrading to Symfony 6.

Symfony Compatibility

• Do not extend the wrong Event class when installed with legacy Symfony but the Symfony contracts happen to be installed

• Allow installation with Symfony 6 components
• Drop support for Symfony 3, minimal version is now 4.3

Cloudflare

• Added Cloudflare ProxyClient Adapter with ClearCapable, PurgeCapable and
  TagCapable. This allows to use FOSHttpCache to invalidate caches on
  Cloudflare. See the "Proxy Client" section of the documentation for how to
  configure the Cloudflare client.

Varnish Cache

• Added a fos_user_context_hash method to be called in vcl_hash when using the user context
  hash mechanism. This can avoid performance problems Varnish can run into when the hash Varys on
  the basic authentication or session cookie.
  If you use the user context, read the updated documentation and call fos_user_context_hash in
  your vcl_hash function.

Noop Client

• Implemented ClearCapable.

Symfony HttpCache

• Added flag on CustomTtlListener to allow keeping the custom TTL header on the response

  something searchable in the code when debugging.
