-- | Creates a new log stream in the specified log group. The name of the log
-- stream must be unique within the log group. There is no limit on the number
-- of log streams that can exist in a log group.
--
-- You must use the following guidelines when naming a log stream:  Log stream
-- names can be between 1 and 512 characters long. The ':' colon character is
-- not allowed.
