Enhancement - "show interface description" alias change

[jhiggins-NZ]

Suggestion:

• Make "show interface description" more user friendly to Cisco & ZebOS engineers.
• Also create IPv4 & IPv6 filtered outputs.

Example:

# show interface description 
Interface       Status  Protocol  Description
ens33           up      up        
lo              up      up

.
.

Change to "show interface brief" and add more options.

Summary of all interfaces

# show interface brief 
Interface       Status  Protocol  Description
ens33           up      up        Mgmt
lo              up      up

Summary of IPv4 interfaces

• Might also be good to alias "show ip interface brief" for the legacy IOS cmd.

# show ipv4 interface brief 
Interface   IP-Address          Status          Protocol
ens33       192.168.1.1         up              up
            172.16.1.50         up              up         
lo          unassigned          up              up

Summary of IPv6 interfaces

• Display the global unicast, ULA or Link Local address(es).

# show ipv6 interface brief 
Interface   IP-Address                  Status          Protocol
ens33       2001:db8:1::1               up              up
            fe80::beef                  up              up         
lo          unassigned                  admin down      down
