Allow run quickstart with extra configs

[xiangfu0]

So users can enable some features e.g. grpc/presto integration etc.
E.g.

pinot.server.instance.currentDataTableVersion=2
pinot.server.grpc.enable=true
pinot.server.grpc.port=8090

It would also be useful if QuickStart could could have config that would allow it to load table and data from an external filesystem directory.
