Update the broker code to pass the logging arguments to child processes.
This also updates the base syslog LogConfig to separate out the
serializable logging arguments from the active logging configuration,
and also updates the LogConfig to no longer require generics when they
aren't used in practice.
Test: passed --log-level to run-mp, verified child processes logs

These tests require initialization of the syslogger via
`openlog_and_get_socket` which requires no other threads in the
process to prevent conflicting file descriptors.
