[system test] Cannot create index on ITEM which has less than 25K documents

possibly related to "build index time out" bug reported yesterday.

1. create 10 buckets, 20 gsi indexes
2. drop index ITEM.IT_ID
3. create index ITEM.IT_ID using gsi – times out.
cbq> create index IT_ID on ITEM(I_ID) using gsi;
{
"requestID": "3ec11e1e-5a59-4b8b-8875-3a686d8365f5",
"signature": null,
"results": [
],
"errors": [

{ "code": 5000, "msg": "GSI CreateIndex() - cause: Request Timeout" }

],
"status": "errors",
"metrics":

{ "elapsedTime": "30.905127433s", "executionTime": "30.904204522s", "resultCount": 0, "resultSize": 0, "errorCount": 1 }

}

I dont have logs yet, will assign this back to gsi team once I collect those.
