rajendra-dendukuri fec80293dd ZTP infrastructure changes to support DHCP discovery provisioning data (#3298)
* ZTP infrastructure changes to support DHCP discovery provisioning data

- Dynamically generate DHCP client configuration based on current ZTP state
- Added support to request and process hostname when using DHCPv6
- Do not process graphservice url dhcp option if ZTP is enabled, ZTP service
will process it
- Generate /e/n/i file with all active interfaces seeking address assignment
via DHCP. Only interfaces that are created in Linux will be added to /e/n/i.
Also DHCP is started only on linked up in-band interfaces.

# Configuration file for /sbin/dhclient, which is included in Debian's
# dhcp3-client package.
#
# This is a sample configuration file for dhclient. See dhclient.conf's
# man page for more information about the syntax of this file
# and a more comprehensive list of the parameters understood by
# dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
# not leave anything out (like the domain name, for example), then
# few changes must be made to this file, if any.
