  Add NFSROOT_SERVER to explicitly set NFS server

Add a new optional configuration option to /etc/fai/nfsroot.conf called
NFSROOT_SERVER which allows users to set the server for NFSROOT
explicitly.

This is needed if the DHCP server is different from the FAI/NFS server
because dracut prefers the DHCP Server Identifier (option 54, which
contains the DHCP server's IPv4 address -- see RFC2132 section
9.7) over any other DHCP option.

This will resolve [731244 in Debian's BTS](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731244).
