IPv6 unit tests should have "ipv6" rather "v6"

[Akihiro Motoki]

At now some plugins do not have IPv6 support and keyword "v6" is checked to skip IPv6 unit tests in these plugins.
"v6" is too short and may be used in a different context.
It is better to have more clear keyword like "ipv6" in IPv6 related unit tests.

@Akihiro, could you please show another context for using 'v6' other than ipv6? I doubt we need a change here at all, please justify.

Reason: I was hoping that Akihiro Motoki (who filed the bug) will replay to Ihar's question. it has been a while now and indeed there's not point for this at the moment.

I am new to OpenStack and interested in working on this bug, if you don't mind, as part of my application process for the Outreachy program. Thanks.

Hi Ema,
The bug is marked as incomplete, means it is missing some information.
As per the review comments on the bug, the importance of its merge is low.
I would suggest you discuss this with @Cedric Brandily or @Akihiro Motoki before proceeding(probably on the IRC)

[Ema (menari2)]

Thanks Reedip. I have also checked with Akihiro Motoki and it makes sense for me to drop this bug. I have picked up another bug- hopefully that one will be available for me to work on.

[Akihiro Motoki (amotoki)]

When this bug was filed, there are various plugins in the neutron main tree.
Now vendor decomposition are almost completed and the need to address this bug significantly decreased (and almost there is no need).
I would like to make this bug "Won't Fix".
