DOC: SPOE is no longer experimental

The SPOE was marked as experiemental since the begining. But, it is no longer
true. This can be an obstacle to its use.

 Now, the aim of SPOE is to allow any kind of offloading on the streams. First
-releases, besides being experimental, won't do lot of things. As we will see,
-there are few handled events and even less actions supported. Actually, for
-now, the SPOE can offload the processing before "tcp-request content",
-"tcp-response content", "http-request" and "http-response" rules. And it only
-supports variables definition. But, in spite of these limited features, we can
-easily imagine to implement SSO solution, ip reputation or ip geolocation
-services.

-    The SPOE filter is highly experimental for now and was not heavily
-    tested. It is really not production ready. So use it carefully.
