Subject: [PATCH] Add debug logging for when room keys are uploaded, including
whether they are replacing other room keys. (#17266)
Fixes: #17013
Add logging for whether room keys are replaced
This is motivated by the Crypto team who need to diagnose crypto issues.
The existing opentracing logging is not enough because it is not enabled
for all users.
