Code Issues Proposed changes

Use client architecture and set bootfile-url for DHCPv6 in inspector

Browse Source 
For DHCPv6 PXE boot, the Client Architecture option uses code 61,
see https://tools.ietf.org/html/rfc5970#section-3.3. Use this
to determine if booting over EFI and set the DHCPv6 bootfile-url
when booting PXE over EFI.

For DHCPv6 PXE boot, the Client Architecture option code (61)
as defined in https://tools.ietf.org/html/rfc5970#section-3.3 is
different than the one for DHCP. This is used to determine
if booting over EFI. This change sets the DHCPv6 bootfile-url
when booting PXE over EFI.
