As per the HLD - sonic-net/SONiC#625 , added config and interface commands.

SONiC CLI per interface configuration command to enable and disable the IPv6 link-local address mode when addresses are not configured manually.

Example:

config interface ipv6 enable use-link-local-only Ethernet24
config interface ipv6 disable use-link-local-only Ethernet24

SONiC CLI global command to enable or disable the IPv6 auto link-local address mode on all eligible interfaces.

config ipv6 enable link-local
config ipv6 disable link-local

Show command to display the link local mode of all interfaces.

root@sonic:/home/admin# show ipv6 link-local-mode 
+------------------+----------+
| Interface Name   | Mode     |
+==================+==========+
| Ethernet16       | Disabled |
+------------------+----------+
| Ethernet18       | Enabled  |
+------------------+----------+
root@sonic:/home/admin#

Depends on:
sonic-net/sonic-buildimage#5584
sonic-net/sonic-swss#1463

I dont think, global implementation is done as per HLD comments (IMO, looping all the available interfaces for global config is a work-around and it doesnt work for any new interfaces after global config), please re-visit.

Global field in device_metadata is not planned as part this PR, it should be an future item.
