MAAS allows specifying BMC IPv6 addresses without brackets ([ ])

[Andrew Forgue]

We're moving to a 100% IPv6 BMC environment due to IPv4 exhaustion and it appears MaaS today only publishes the IPv4 BMC info to the power configuration.

I can enter an IPv6 address into the IP address field of the IPMI power type but it just hangs on "checking power" and eventually returns `Error: Failed to power query 2001:ffff:ffff:ffff:4e38:d5ff:fe04:3a29: 2001: invalid hostname`

The ipmitool command on the rack controller seems to support it, no idea if that's relevant at all.

```
connect(3, {sa_family=AF_INET6, sin6_port=htons(623), inet_pton(AF_INET6, "2001:ffff:ffff:ffff:4e38:d5ff:fe04:3a29", &sin6_addr), sin6_flowinfo=htonl(0), sin6_scope_id=0}, 28) = 0
```

How did you add the IP address? Was it between brackets ? Can you try adding it between brackets?

instead of something like:

2001:ffff:ffff:ffff:4e38:d5ff:fe04:3a29

Try adding it like:

[2001:ffff:ffff:ffff:4e38:d5ff:fe04:3a29]

Yes, this seems to work. However I can't test it end-to-end since I believe the network ACLs are missing return traffic from the IPMI device.

It does, however accept the input and I see the process on the rack controller contacting IPMI on the proper (IPv6 IP address) repeatedly. I'll update once I get the ACL fixed.

I confirmed that putting the IPv6 in brackets works.

Is this still an issue in a more recent MAAS (3.2 or later)?
