Support mkdir option for the output file plugin fluentbit

### Is your feature request related to a problem? Please describe.

If we need to write into a path in the ClusterOutput file plugin , we need to explicitly mount all the paths recursively in the FluentBit CRD.

### Describe the solution you'd like

FluentBit file plugin provides a mkdir option to create directories recursively with the right permission. This option is missing in the ClusterOutput file plugin of fluentbit. Request to add support for this.
