Invalidate Tag immediately instead of when command finishes

[stevenmusumeche]

I have a long running process that invalidates tags in Varnish. I noticed that the tags seem to be accumulated and sent all at once when the command ends. Since I need this task to run for hours, Is there a way to invalidate the tags immediately when the invalidateTags command is called?

i created FriendsOfSymfony/FOSHttpCache#219 to better explain the invalidateTags method. you need to inject/fetch the CacheManager service and call flush after invalidating tags. this will trigger the invalidation requests immediately and should clear the list of tags to invalidate at the same time.

please check if things work as expected, i am not aware of other people having used invalidation in long running processes.

I ran it through the debugger and it works as expected. The tags are sent to varnish and the queue is cleared.
