[Helm] add support for additionalVolumes

[drish]

Hello,

I have been working on getting JMX Java Agent working with my Trino installation and came across this issue where:

In order to get Trino JMX Java Agent working, the .jar file needs to be present on the trino machines, and right now the
charts do not support additionalVolumes so that I can add this file as a volumeMount.

Is there an alternative way to do it, or it will actually depend on something like additionalVolumes being included in the Chart ?

Thank you.

I think with the merge of #129 this issue is now resolved?
