[libvirt] [PATCH v1 1/3] migration: add migration_host support for Ipv6 address without brackets

when specifying migration_host to an Ipv6 address without brackets, it was resolved to an incorrect address, such as: tcp:2001:0DB8::1428:4444, but the correct address should be: tcp:[2001:0DB8::1428]:4444 so we should add brackets when parsing it.
