Artem Bilan 8a7cf6cc65 INT-4464 Check ZKMetadataStore.running before use ...

JIRA: https://jira.spring.io/browse/INT-4464

A `ZookeeperMetadataStore.get()` is based on the `this.cache` variable.
This one is initialized in the `start()`.

* Assert `isRunning()` in the `get()` before using.

**Cherry-pick to 5.0.x and 4.3.x**
