The IPFS bootstrap nodes seem to use 1024 bits RSA keys

[tomaka]

While 2048 bits keys are default and would be preferred.

@lgierth @kyledrake what's the main reason why we don't use 1024 bits keys in our Infrastructure nodes?

Ping @lgierth and @kyledrake

Historic reasons -- we bumped the default to 2048 at some point.

There are a few 2048 bit peerIDs in the default bootstrap list that I added like 9 months ago - we should:

1. start using them, i.e. start the respective nodes.
2. remove the QmSoL nodes from default bootstrap.
3. hopefully in a year or five be able to shut the QmSoL nodes down.

@lgierth can we have a list of all the nodes and their keys here?

New nodes (not running yet, just PeerIDs):

• /dnsaddr/bootstrap.libp2p.io/ipfs/QmNnooDu7bfjPFoTZYxMNLWUQJyrVwtbZg5gBMjTezGAJN
• /dnsaddr/bootstrap.libp2p.io/ipfs/QmQCU2EcMqAqQPR2i9bChDtGNJchTbq5TbXJJ16u19uLTa
• /dnsaddr/bootstrap.libp2p.io/ipfs/QmbLHAnMoJPWSCR5Zhtx6BHJX9KiKNN6tpvbUcqanj75Nb
• /dnsaddr/bootstrap.libp2p.io/ipfs/QmcZf59bWwK5XFi76CZX8cbJ4BhTzzA3gU1ZjYZcYW3dwt

Old nodes:

• QmSoLPppuBtQSGwKDZT2M73ULpjvfd3aZ6ha4oFGL1KrGM (in default bootstrap)
• QmSoLnSGccFuZQJzRadHn95W2CrSFmZuTdDWP8HXaHca9z

@lgierth is it possible we could have a similar schema as the old QmSoL? Maybe a different one, but was handy to immediatly see if a node was a bootstrap node or node. Same with the gateways.

They're already in go-ipfs's default bootstrap. I also think that at one point we'd break from that scheme anyway when there's a situation where we need to quickly add new nodes (brute-forcing these took a day or three).
