What happened?

Description

Data stream attributes are not sanitized, resulting in non-compliant data stream names. Sanitization should be implemented according to https://www.elastic.co/guide/en/ecs/current/ecs-data_stream.html. There is also an implementation of DS fields sanitization in ES, but in this implementation there is in incorrect handling of an edge case where string limit should be 100 unicode characters instead of 100 bytes.

Steps to Reproduce

Supply a value with - in resource attributes data_stream.dataset or data_stream.namespace

Expected Result

The value is sanitized so that the resulting data stream does not contain -

Actual Result

The resulting data stream contains -.

Removing needs triage as this was filed by a code owner and makes sense to me.
