[Custom Filestream] Add an option to route collected data to streams #14658
Description
- Relates [streams] Confirm setting the target index to "logs" routes data to streams beats#45505
- Relates [streams] Allow Beats run by Elastic Agent to route data to the "logs" index beats#45506
Add a user selectable option to the Custom Filestream integration that sets index: "logs" for the input instead of setting the data stream fields. This will require elastic/beats#45506 to be addressed first if we want to use the index: "logs" setting in the input configuration.
An alternative that may work right away would be to have the option generate an add_fields processor to override the default logs-generic-default index that will be configured when the data_stream fields are omitted. If this works it is preferable since it won't require an Elastic Agent upgrade to use.
