Adding log volume and posibility to provide pod annotations

[Nierhoff]

Hi,

I am working with log data collections from infinispan. I have added 2 elements to the helm chart.

1. A volume dedicated to logs, which can easy be mounted into a sidecar.
2. Posible to provide custom annotations, this could for example be for opentelemetry injection of sidecar og code level injection.

What do you think ?

log-volume seems a nice feature but It would be better to not change the default behaviour: could you change to be enabled by the user? maybe via a deploy.container.logVolume option.

pod annotations looks good

I have reverted log volume. If it is not a default i would rather implement a generic additional volumes in another PR
