Distributed Session Management #7529 #7594

[rymsha]

• ignite was updated to latest version. To make sure I don't use deprecated API
• worked around ignite bug where it uses wrong classloader for serialisation of ignite internal classes (this is due to conflict between ignite and OSGi which classloader to use)
• removed ignite XP "Cluster" abstraction, because not all nodes will be ignite cluster (if any)
• javax cache updated to version 1.1.1 (now Apache license). Removed rebundle as it is now correct bundle by itself. It is potentially a breaking change, but very unlikely because code is supposed to import 1.x version of javax.cache package.
• fixed SessionWrapper: it had race conditions for session creation and was storing reference to potentially expired session
• fixed JettyActivator to wait for all dispatchers to be ready. Before it was potential race.
• introduced IgniteSessionStoreFactory (OSGi service) and made IgniteSessionStore OSGi independent. This make multiple dispatchers work again - before they were sharing SessionStore singleton and fail on startup
• worked around Jetty vs Ignite conflict which deserializer to use
• added package import so Auth info deserialization works (OSGi prevents not imported classes to be deserialized).

Can you guarantee compatibility after upgrading Osgi?

[rymsha]

I tested it. It should be fine. We are using R7 in runtime already. But compile with R6.
But it is not a real brunch where new OSGi is introduced. See #7374

Don't close it. Many ideas can be used for Hazelcast
