[WIP] feat: adding ability to specify a key type to use

[ETeissonniere]

Depends on libp2p/js-peer-id#65

The following PR is enabling the possibility to specify the key type to use while running the jsipfs init command. Even if it isn't really useful at the moment, it open the path for a more modular implementation regarding key management.

Hi @developpsoft. Thank you for going ahead and taking a stab at this.

I'm concerned that merging something like this PR would create confusion amongst our users as it would present an option that is not implemented fully nor documented anywhere else with a roadmap to actually get it done.

I would be very happy to guide you if you want to lead the development of such feature, beware however that this requires touching pretty much the entire stack.

Hi @diasdavid thanks for the follow up! Yeah indeed I agree with you, let's wait.

Hi @diasdavid I finally have some spare time, so if you still want to lead me on this I am ready 😉

Awesome @developpsoft ! Let's start with something of smaller scope and I say this because this multikey support is something also still being figured out and merged in go-ipfs and I would rather make sure that all decisions have been made than having to guide you through flux.

Wanna pick some of the issues available here https://github.com/ipfs/js-ipfs/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22 to get started and familiar with the codebase?
