🐛 [firestore-bigquery-export] Backfill through lifecycle events

[pr-Mais]

Opening this issue to track the progress on fixing the issue reported on #2000, #2003, and #2021.

We are working on finding a better approach to do backfilling for this extension, until then the feature is disabled (you will not find the option to import existing docs on install starting from v0.1.48).

You can still import your existing data through the import script.

@pr-Mais Hi there, thanks for sharing the import script. May I ask if it's possible to use it in order to backfill data from a Firestore collection residing in a database other than the (default) one? The script works fine if I specify a collection in (default) database, however it fetches 0 records for collections residing in other database and I can't seem to find a way to specify a valid collection path.

Plus 1 to database other than (default)
