GEODE-9409: wait for PdxRegistry before executing create region (#6743)
* GEODE-9409: wait for PdxRegistry is finished before executing create region
> NullPointerException while create region during server restart

> Key: GEODE-9409
> URL: https://issues.apache.org/jira/browse/GEODE-9409
> Project: Geode
> Issue Type: Bug
> Components: gfsh, regions
> Reporter: Mario Kevo
> Assignee: Mario Kevo
> Priority: Major
> Labels: pull-request-available
>
> If the "create region" command is executed while the Geode server is
> restarting it will fail with NullPointerException on that server.
> It happens for persistent regions as it tries to findDiskStore but in that
> method, it first tries to get PdxRegistry from the cache and create a
> persistent Region on that. But in that case, when the cache is creating(it
> takes some more time if the server is restarting), if the command is executed
> fast it happened that creating cache is not finished and pdxRegistry is null,
> so every method executed on that will throw NullPointerException.
