Bump 10.4.0 dev

See merge request !1009

When we did the linting changes, these exceptions were
changed to `raise ... from None`.  This removed the
default exception chaining.  We want the chaining here to
better report startup errors, so do it explicitly.

Reduce the time we wait for `get_server_port_via_pid` so
that it is less than the time we wait for `pre_init`
to report the port.  This way we can see the exception from
`get_server_port_via_pid` instead of just a generic port not
available error.
