add model_incremental_strategy to track_model_run

[MichelleArk]

Resolves https://github.com/dbt-labs/dbt-core/issues/10761 https://github.com/dbt-labs/iglu.getdbt.com/issues/28

Problem

In order to track adoption of the new microbatch strategy, we'll need to track which incremental_strategy configs users are setting.

Solution

Obtain the optional incremental strategy config and plumb it through the tracking event.
