FreeBSD: Support ConfigDrive
Add support for freebsd reading config drive. Primary work is related to re-factoring mount_cb to not be so linux specific. Other changes: * declare PATH in freebsd initscripts * list dependency on e2fsprogs (for blkid) * enable ConfigDrive in freebsd config * hosts.freebsd.tmpl added
