What for collection named 'oauth2_txn' and 'oauth2_txn.stash??
Documents in this collection remains forever, no expire date.
is it ok delete this docuemt in 'oauth2_txn' and 'oauth2_txn.stash collection?

mongo package of oauth2 is using multi-doc transaction to store data into multiple collection at once.
because below version 4 of mongo doesn't support transaction.

https://pkg.go.dev/labix.org/v2/mgo/txn#Runner

to use txn package by mongo package
it should define transaction collection named oauth2_txn

and txn package is making .stash collection itself.

so oauth2 package is making 2 collections named oauth2_txn, oauth2_txn.stash.
but anyway oauth2 doesn't know 2 collections is going to create or not.
