When a filter is configured to conditionally forward, and it is configured to handle FORWARD dispatches as well, and it prevents infinite forward loops by either extending OncePerRequestFilter or otherwise using request attributes, this can result in infinite forward loops in WebClient tests using MockMvcWebConnection. This change will restrict the maximum number of forwards in MockMvcWebConnection to 100. Closes spring-projectsgh-29483

@manthanb thanks for the contribution. I think that throwing an exception as proposed in the original issue would be better, wdyt? The message can mention that there is a probable infinite loop and that it forwarded 100 times.

This change restricts the maximum number of forwards in MockMvcWebConnection to 100, in case a forward is configured in a way that causes a loop. This is necessary in HtmlUnit backed tests, unlike in classic MockMvc tests in which the forwards are not actually resolved.
