Description: Add functionality to import and export ipfs keys

Please add commands to ipfs in order to be able to export and import (private) keys (à la gpg).

If there is no other suggestion something like ipfs key export <name> and ipfs key import <file> --name=<name> would do. They could possibly be adapted to import/export only the public key.

Reasonable usecase

I use ipns to publish my personal blog, and I'd like to be able to publish to it from more than one machine. Moreover, if my pc break I wouldn't be able to update my blog any more.

Attempt at finding a solution

Searching online I was not able to find a way to export my keys (and ipfs help shows nothing) except https://github.com/tswindell/ipfs_keys_export that apparently does not work since ipfs config Identity.PrivKey gives error Error: cannot show or change private key through API.

Quick solutions?

Apart from implementing these (which I guess may take some time), is there any hack I can now perform to be able to import/export keys? For example, are they saved in a specific file with a specific well behaving format?
