HiddenHttpMethodFilter can be problematic as it causes early
consumption of a request body if the body may contain parameters. This
happens as the filter needs to read the parameters to see if an
_method parameter is present. The filter is only beneficial for web
applications that are the hidden HTTP method functionality but is
potentially detriimental to all applications that are not. As such
we no longer believe that it should be enabled by default and users
should be required to opt in.

Previously, if a user defined a MongoDbFactory bean but did not define
a client bean, MongoDataAutoConfiguration would back off leaving the
context without a MongoTemplate, etc.

This commit reworks the auto-configuration so that only the
auto-configuration of a MongoDbFactory is dependent on the existence
of a Mongo client bean. Auto-configuration of the other components
that depend on a MongoDbFactory will now continue in the absence of a
Mongo client bean.

Update `ValidationBindHandler` so that a custom `AbstractBindingResult`
is used rather than `BeanPropertyBindingResult`. This allows us to
validate results, regardless of whether the actual bound instance has
public getters or setter.
