[improve][test] Use configured session timeout for MockZooKeeper and TestZKServer in PulsarTestContext

[lhotari]

Motivation

After #23988, MockZooKeeper is correctly single threaded and an injected delay will block the execution of this code in ZKSessionWatcher:

pulsar/pulsar-metadata/src/main/java/org/apache/pulsar/metadata/impl/ZKSessionWatcher.java

Lines 108 to 115 in 6e8c349

	try {
	zkClientState = future.get(tickTimeMillis, TimeUnit.MILLISECONDS);
	} catch (TimeoutException e) {
	// Consider zk disconnection if zk operation takes more than TICK_TIME
	zkClientState = Watcher.Event.KeeperState.Disconnected;
	}
	checkState(zkClientState);

This will trigger a ConnectionLost session event. That's why a delay should be kept under 2000 ms.
Currently MockZooKeeper's session timeout is hard coded to 30000ms and the check interval is 1/15 of this, therefore 2000ms.

When there's a test that blocks the ZooKeeper thread for more than 2000ms, it will result in a ConnectionLost event.
This PR makes the session timeout configurable and it's possible to increase the session timeout for tests where it's necessary to use a longer session timeout to avoid ConnectionLost session events.

Modifications

• refactor the code in PulsarTestContext to postpone creation of the instances after the configuration including the configured session timeout is available
• also configure other MetadataStoreConfig settings and pass them from the ServiceConfiguration instance
