Extend `JsonContentAssert` with `hasJsonPath` and `doesNotHaveJsonPath`
methods which can be used to check the path regardless of the value it
may or may not contain.

Prior to this commit there wasn't an easy way to assert that the
Jackson `@JsonInclude(JsonInclude.Include.NON_NULL)` annotation was
applied since `assertDoesNotHavePathValue` would pass for both
`{"name" : null}` and `{}`.

Closes gh-17608

This commit updates the `RouteMatcher` configuration after the latest
Spring Framework changes. The default route matcher implementation based
on the `PathPattern` infrastructure is now tailored for the messaging
