Timeout for reactive Spring Session is configured using Servlet-specific property

[vpavic]

Configuration of session timeout for reactive Spring Session repositories (Redis, MongoDB) uses
server.servlet.session.timeout which is advertised as Servlet-specific configuration property.

SessionProperties populates timeout property from org.springframework.boot.web.servlet.server.Session via ServerProperties, which is OK for Servlet apps but very confusing and not obvious for WebFlux apps.

Do we want to change this in 2.0.x or 2.1?

It's an oversight so, depending on the resolution, I'd like to see that in 2.0.x.
