Allow customization of sessionId, e.g. hazelcast-session

[trydofor]

Expected Behavior

Make it possible to customize the sessionId instead of the UUID.

Current Behavior

hazelcast-session, for example, use UUID as sessionId, cannot override or customize.

① let final class HazelcastSession to public

spring-session/spring-session-hazelcast/src/main/java/org/springframework/session/hazelcast/HazelcastIndexedSessionRepository.java

Line 358 in 3ead793

final class HazelcastSession implements Session {

② extract MapSession cached = new MapSession(); to method can be override

spring-session/spring-session-hazelcast/src/main/java/org/springframework/session/hazelcast/HazelcastIndexedSessionRepository.java

Lines 247 to 253 in 3ead793

	public HazelcastSession createSession() {
	MapSession cached = new MapSession();
	cached.setMaxInactiveInterval(this.defaultMaxInactiveInterval);
	HazelcastSession session = new HazelcastSession(cached, true);
	session.flushImmediateIfNecessary();
	return session;
	}

I think it's duplication of #2258
