Add query row to exportable controls

[srclosson]

The PR adds the QueryEditorRow control, which acts as a single row for which you can add controls as children.

What about:

<InlineField label="Query type" labelWidth={14} grow={true} tooltip={queryTooltip}>
            <Select
              options={siteWisteQueryTypes}
              value={currentQueryType}
              onChange={this.onQueryTypeChange}
              placeholder="Select query type"
              menuPlacement="bottom"
            />
          </InlineField>

if we need this on things older than 7.3... maybe copy it from grafana/ui?

i am slightly skeptical of this whole repo... unless it has planned obsolescence built in :)

Yeah, that's fair. I'm sure it's better than what we have, but maybe not quite as good as we can be. But it's a step forward. Actually, there are a few things I can do better with this control.
