core.certmanager: Add TLS 1.3 cipher suites to Mozilla TLS presets

core.certmanager: Presets based on Mozilla SSL Configuration Generator ssl_preset = "modern"

moduleapi: Support stripping of multi-word from module names The goal is to allow module:provides("foo-bar") with a mod_foo_bar_ prefix being stripped. It will break any existing modules that use a prefix and have hyphens instead of underscores. No such modules are known.

adminstream: fire disconnected event on lower layer disconnect This may in theory cause multiple disconnect events for the adminstream client, if the only code using that wasn't calling os.exit right away. Hence, this should be a good enough partial fix for #1671. It is not a full fix, because the shell will only notice the disconnect after one has hit enter in the input; until then, it is stuck in a read() call to stdin and completely oblivious to the disconnect.

mod_pep: Wipe pubsub service on user deletion Data is already wiped from storage, but this ensures everything is properly unsubscribed, possibly with notifications etc. Clears recipient cache as well, since it is no longer relevant.

mod_pep: Prevent creation of services for non-existent users Using a dedicated service should give identical behavior, except for a possible timing difference in the user existence lookup.
