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 any non-null result returned by
the parent `onFailure` method triggers re-validation.

Fixes gh-17421

Previously, the context path was set to an empty string. The led to
Jetty logging a warning about an empty context path and then using
/ instead.

This commit avoids the warning while leaving the context path's end
result unchanged by setting the context path to /.

Previously, a regular expression of /./ was used to replace /./ with
/.  The '.'' in the expression matches any single character so the
replacement was more broadly applicable than it should have been. For
example, /a/ would be replaced with /.

This commit uses Pattern.LITERAL to compile the regular expression
from the CURRENT_DIR (/./) contant. This allows the constant to be
used to check for occurances of /./ in the string before attempting
replacement, while also ensuring that the '.' is treated literally.
