Fluent bit helm chart does not have provision to configure automountserviceaccounttoken

[muralisankar32]

As per CIS compliance, Service accounts tokens should not be mounted in pods except where the workload running in the pod explicitly needs to communicate with the API server. To ensure pods do not automatically mount tokens, set automountServiceAccountToken to false.

Currently fluent bit helm chart does not have a provision to set this variable in the helm chart.
