Support uncompressed ipv6 address and abbreviated ipv4 address

Browse Source 
Now neutron supports zero-compressed ipv6 address like
'2001:db8::10:10:10:0/120' and unabbreviated ipv4 address
like '10.0.0.0/24'.
This path will make neutron also support uncompressed ipv6
address and abbreviated ipv4 address. for example:
1, uncompressed ipv6 address like 'fe80:0:0:0:0:0:0:0/128'
2, ipv6 address with multiple consecutive zero like
   '2001:0db8:0:0:1::1/128' or '2001::0:1:0:0:1100/120'
3, abbreviated ipv4 address like '10/24'
