Description

It'd be helpful to be able to execute a query from a file in the shell. For example:
run mytable /path/to/query.json

I think we could also provide a simple utility that does the writing, to make it easy to write to a logger... e.g.
QueryWriter.toJsonString(BlurQuery q) {
...
TProtocol p = new TJSONProtocol(new TIOStreamTransport(...));
q.write(p);
...
}

Then the shell can just inflate the object and run the query, e.g.
BIS in = new BufferedInputStream(new FIS(query.json));
TProtocol p = new TJSONProtocol(new TIOStreamTransport(in));
TBase<BlurQuery, BlurQuery._Fields> tbase = new BlurQuery();
tbase.read(p);

It'd be helpful for debugging large queries with unique characteristics (e.g. loads of facets).
