Log a warning if prefix or suffix exclusions are used in web.xml or hst:hosts configuration

As a result of HSTTWO-2273 the web.xml init params for prefix exclusions are not used any more, and as a result of webresources epic, the suffix exclusions from hst:virtualhosts have become redundant : It is much better to bootstrap it from the HST to the hst:default/hst:sitemap. This also makes it possible to make the /binaries prefix configurable by sitemap name if we want (using a sitemap identifier for binaries) and then invoke the binaries servlet with a preview or live jcr session

If you do not want to use or cant use a sitemap item for an exclusion (for example because you hit the HST over an ip address for say /ping which is not a configured host), you must use a comma separated hst-config.property
filter.prefix.exclusions or
filter.suffix.exclusions
