add an ability to print results only in cbq

It would be very useful to have an ability to print in the cbq tool only the results of the request for scripting purposes. without the metadata of the request. especially in places jq tool is not available.

for example currently this line, takes a query from a file, and print the results to another file, quietly

/opt/couchbase/bin/cbq -e http://hostname:8091 -q -u username -pretty=false -l cbq_log.txt -f query.n1ql -o cbq_out.txt

resutls are printed as follows:

{

"requestID": "0b965c25-ff59-49ca-9362-67a563cf4dae",

"signature": {"address":"json","name":"json"},

"results": [

{...},

{...}

],

"status": "success",

"metrics": {"elapsedTime": "18.079943038s","executionTime": "18.07984059s","resultCount": 10,"resultSize": 688}

}

instead of maybe just the array of the resutls,

which would run as a command

/opt/couchbase/bin/cbq -e http://hostname:8091-q -u username -pretty=false -nometa=true -l cbq_log.txt -f query.n1ql -o cbq_out.txt

[

{...},

{...}

]
