Configuratin for ejb strict-max-pool is confusing regarding derive-size and max-size

The strict-max pool can be set for automatical configuration with
derive-size (none|from-worker-pools|from-cpu-count) or set the number of pool-entries by use max-pool-size.

If derive-size is set the use of max-pool-size will throw an error during start that the use is exclusive.
But as derive-size="none" mean the same as if the attribute is not set it will be confusing.

• not clear what the pool size is then (I checked it is the default max-pool size =20)
• confusing if it is reset by cli, attr derive-size need to be removed to use max-size

So finally "none" is useless and should be removed.
