@chen-keinan Does it make sense to add --skip-java-db-update for SkipDBUpdate to already existing --skip-db-update?

trivy-operator/pkg/plugins/trivy/flags.go

Line 60 in d2825cd

return "--skip-db-update"

@ahalay java-db-update refer to java component index data not vulnerability.
it occur only when trivy cli detect jar files inside the container.
Skipping it functionality should be do en in a separate flag as it does a different thing from db-update
