(Add) Peer support IPv4 & IPv6 at the same time

[Alkl58]

Draft - Proof of concept

Not sure if this should be merged - might have implications which I have not caught.

Notes:

• checkMinInterval has to be changed or disabled
• supervisor config has to have at least --tries=2 (tested with --tries=3)
• No incorrect stats (download/upload) has been seen during testing
• Maybe we want to only give ipv6 peers to peers who also have ipv6

Missing (will be added to this PR):

• Views
• Livewire

How does it work:

• qBittorrent:

1. Each Client IP generates a seperate request
2. All requests land into the queue with the WithoutOverlapping lock, so that only one get's processed at a time
3. The other requests will time out and re-run after ~10-15s, each job will find the same "old" peer and add the missing ip addresses (IPv4/IPv6)

• ruTorrent:

1. The IPv4 header will be send into a seperate ip field, when announcing via IPv6
2. Same as qBittorrent, only that a single job will run, as the request has both IP addresses (IPv6 via client ip / IPv4 via ip field)
