    Executes an select query on database "database" created from provided
    arguments measurement "measurement", fields to select "fields", optional
    "where" clause, grouped by "group_by" and empty values filled with
    "fill", ordered by "order_by" with number of results limited to "limit"
    with offset "offset". To limit number of returned series use "slimit"
    with offset "soffset". If "into" parameter is provided the result of the
    query will be copied to specified measurement. If "epoch" is provided
    the returned "time" value will in Unix epoch format. Optional
    "chunk_size" can be provided to override the default value of 10,000
    datapoints.

    The required "on_success" code reference is executed if request was
    successful, otherwise executes the required "on_error" code reference.
