Add control over bundle "version in db" check in pasring loop

### Body Right now, in order to protect against multiple DAG processors becoming out of sync and parsing different versions of a bundle at the same time, we are constantly querying the db for the currently known bundle version. We, however, need a way to turn that down a bit, both for single DAG processor and multiple DAG processors. ### Committer - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project.
