use java command wrappers and params to create plates

[labkey-chrisj]

Rationale

This adds command/response wrappers to create plate sets used in biologics for now, (I'm not sure if this will be limited to lims modules or not, so creating here)

The reason to create via API at this point is that the UI doesn't yet support creating child or parent-type plate sets, this allows us to get automated regression coverage in place until it does

Just a small nit about some odd JSONObject behavior.

[labkey-tchad]

These null checks actually aren't necessary. Much to our chagrin, JSONObject doesn't allow null values. A put with a null value actually removes any existing entry and does nothing if there is no existing entry.

Suggested change

	JSONObject json = new JSONObject();
	if (_name != null)
	json.put("name", _name);
	if (_description != null)
	json.put("description", _description);
	if (_type != null)
	json.put("type", _type);
	if (_id != null)
	json.put("rowId", _id);
	if (_parentPlateSetId != null)
	json.put("parentPlateSetId", _parentPlateSetId);
	return json;
	JSONObject json = new JSONObject();
	json.put("name", _name);
	json.put("description", _description);
	json.put("type", _type);
	json.put("rowId", _id);
	json.put("parentPlateSetId", _parentPlateSetId);
	return json;

Thank you! (I didn't know that, it feels good to learn something new)
This probably means we have a lot of other writing-of-json to update accordingly; in writing this I followed the pattern from NotebookParams
