With the upgrade to the new Couchbase SDK and the related changes in
Spring Data Couchbase, CacheManagerCustomizer can no longer be used to
customize the Couchbase cache manager as it is an immutable class.

This commit introduces a dedicated callback for the
CouchbaseCacheManagerBuilder that is used by the auto-configuration and
update the documentation to refer to it with a sample usage.

Previously, UrlPathHelper's full path optimization was enabled when
there was a dispatcher servlet mapped to /. The UrlPathHelper is used
across Spring MVC and if there are multiple dispatcher servlets they
all share the sample UrlPathHelper. This meant that any additional
dispatcher servlets mapping to locations other than / would not be able
to map requests correctly as the UrlPathHelper would use the full path,
ignoring the url mapping of the dispatcher servlet.

This commit updates the MVC auto-configuration so that use of the full
path is only enabled if there's a single dispatcher servlet
registration.
