Spring Session integration module

[Данилов Семён]

Hello, Igniters!

I recently submitted a pull request to the Spring Framework's spring-session repository adding Apache Ignite integration module so that users will be able to store HTTP sessions in Ignite backed repository.

If you know any Spring committers that can review and merge these changes, please let me know.
You can also help if you leave a thumbs up at the pull request: https://github.com/spring-projects/spring-session/pull/1730.

Kind regards,
Semyon.
