service: drop special HTTP server target, as it is a bad idea anf Fedora specific
This was premarily intended to support the LSB facility $httpd which is only known by Fedora, and a bad idea since it lacks any real-life usecase. Similar, drop support for some other old Fedora-specific facilities. Also, document the rules for introduction of new facilities, to clarify the situation for the future.

+ * Rules regarding adding further high level targets like the above:
+ *
+ * - Be conservative, only add more of these when we really need
+ * them. We need strong usecases for further additions.
+ *
+ * - When there can be multiple implementations running side-by-side,
+ * it needs to be a .target unit which can pull in all
+ * implementations.
+ *
+ * - If something can be implemented with socket activation, and
+ * without, it needs to be a .target unit, so that it can pull in
+ * the appropriate unit.
+ *
+ * - Otherwise, it should be a .service unit.
+ *
+ * - In some cases it is OK to have both a .service and a .target
+ * unit, i.e. if there can be multiple parallel implementations, but
+ * only one is the "system" one. Example: syslog.
+ *
+ * Or to put this in other words: .service symlinks can be used to
+ * arbitrate between multiple implementations if there can be only one
+ * of a kind. .target units can be used to support multiple
+ * implementations that can run side-by-side.
