Fixes dnsmasq host file parsing with "addr6_list"
This patch fixes:
- The IPv6 tag added in the "host" file if is supported in
dnsmasq. That shifts all other parameters in the register.
- IPv6 registers can have more than one IP address; in this
case, the method "_read_hosts_file_leases" should return a
tuple per IP address.

Title:
[DHCP] IPv6 "addr6_list" change the "host" file format
Status in neutron:
Fix Released
Bug description:
This bug could be divided in two:
1) IPv6 tags feature [1] introduces, if supported by the dnsmasq version, a
new element in the "host" file, the tag:
fa:16:3e:6b:c1:97,tag:dhcpv6,host-fe32-dead-beef--5.localdomain,[fe32:dead:beef::5]
That will shift all other parameters and should be considered when
parsing this file.
2) The IPv6 registers (lines in "host" file) can have more than one IP
address. Each one should be registered as a new item in the set
returned in [2]
