A new option has been added for configuration of SMTP timeout:
- notifications.smtp-timeout

During tests, we can change this timeout to be small, so we aren't
depending on hardware-based RNG to pass the timeout.

Without a timeout, users can run into a long-running test for no
particular reason.

People can change comaintainer ownership to suspended users if they
want to.

Suspended users cannot login, so there is no breach of security
here. It does make sense to allow ownership to be changed, imo.

Closes #339

Instead of allowing an exception to propogate through the framework
routes, catch it and log out an error about notifications not being
sent.
