Add the CloseQuery function to close the query handle?

[shfhp]

connection.go

func (c *Connection) Query(query string) (RowSet, error) {
bquery := beeswax.Query{}

bquery.Query = query
bquery.Configuration = []string{}

handle, err := c.client.Query(&bquery)

if err != nil {
	return nil, err
}
**c.handle = handle**

return newRowSet(c.client, handle, c.options), nil

}

*func (c Connection) CloseQuery() error {
if c.handle != nil {
c.client.CloseInsert(c.handle)
c.handle = nil
}
return nil
}

At the moment I do not have access to an Impala server to do any testing. In principle, this looks good, feel free to submit a pull request.
