Hack SshDaemon to not use SecureRandom during tests

We previously needed 8 bytes of data from a SecureRandom in order to
start an SSH daemon. Unfortunately, sometimes machines run out of
entropy, for example when running the Gerrit test suite several times
in a row.

Add an undocumented configuration option to use a different Random
factory for Apache SSHD that uses a hard-coded seed instead of
depending on SecureRandom. Unfortunately, because SshDaemon is
constructed using Daemon's injector stack, we can't easily modify its
modules to swap out the provider, so a configuration option is the
easiest solution.
