Missing LLDP migration

Ticket:	#4978
Fix #94, generate and save the sshd host keys.

Before this was being handled by hacks to FreeBSD in TrueOS.

To remove the hack, instead move the parts to extract the
generated keys to ix-sshd which runs before /etc/rc.d/sshd and
move the parts that save the keys to a new script ix_sshd_save_keys.

Split lldp migration up

- account_* tables are not available at the time the service migration
  is run. While this works for a running system, it doesn't work on
  fresh installs. If there is a better way to do this, do it ;-)
- In order to make this work on an existing system with the lldp migration
  already in place, I had to remove the entries in the account_bsdusers
  and account_bsdgroups tables for the ladvd user, and drop the
  services_lldp table. I don't consider this a bug since it won't happen
  to those who did not run the migration already.
