DataStorm demos build fixes

[pepone]

This PR fixes the DataStorm demos to use the updated constructors from zeroc-ice/ice#4462

For most demos they use a config file, but none of the properties in the config file was required, for those I just remove the config files and updated the code to use the argc/argv overload.

For the DataStorm/node demo I move the required properties to the Reader and Writer, which requires a bit more code.

Pull Request Overview

This PR updates DataStorm demo applications to use the new constructor pattern from Ice framework pull request #4462. The changes remove configuration files that contained only optional properties and update the code to use direct constructor calls.

• Removes config files with only optional/commented properties from most demos
• Updates DataStorm::Node constructors to use argc/argv overload instead of config file parameter
• Adds explicit property configuration in the node demo which required specific connection settings

There are two spaces after 'properties.' in the comment on line 21. Should be a single space.

Suggested change

	// Default properties. Communicators used by DataStorm must have a property set that can use the "DataStorm"
	// Default properties. Communicators used by DataStorm must have a property set that can use the "DataStorm"

We should improve this "reserved property" name syntax. It's not elegant.

[bernardnormier]

We should rework this code to be consistent with Greeter and the other demos. For a follow-up PR.

[bernardnormier]

We should use {...} for constructors. For a follow-up PR.

I will review this demos in a follow up PR, we haven't done much updates on them.
