fix(sqp): Request metrics chunk in the default queryer

When a client was created using svrquery.NewClient() then c.Query() was
executed only server info chunk was going to be requested by default.

This fix adds the metrics chunk to the requested chunks used in the
default queryer.

This was missed from the previous commit.
