commons-pool2 is also used by GraphiteWriter

[LasneF]

done , add a comment on it to be more precise
I currently do not use Graphite ( I use Console Writter or ... a an incomming Custom Outputwriter) so i do not need this dependency

This will require to bump embedded-jmxtrans to 1.1.x as it may cause backward compatibility issues. Anyway, I should already have bumped to 1.1.x when I migrated from commons-pool to commons-pool2.
