Griffin Smith 0d1980f2d6 feat(xanthous/server): Load host secret key from disk
Rather than randomly generating a new host key every time we run the
server, load the host's secret key from a file on disk at startup, so
that clients don't have to disable host key verification to connect
every time we restart.
