Make `ockam identity show` command work without creating nodes

[mrinalwadhwa]

Currently:

> ockam enroll
...
> ockam identity show
No such node available. Run `ockam node list` to list available nodes

After enroll there is already an identity and it is stored in the default_identity key of our config file.

Desired:

In the above case > ockam identity show should show the default identity.

I made a start at this in https://github.com/rtsuk/ockam/tree/default_identity. I think it is correct for the command's full option, but I'm not sure how to covert the identity in the config file into a identity ID.

@rtsuk thank you for spending time on this! Would you mind turning your branch into a draft pull request? I'll try to help with comments there.

Roughly, something like this should work:

let vault = Vault::create();
let identity = PublicIdentity::import(&serialized_identity, &vault);

Will do. The pull request template had a lot of text and the coffee hadn't quite kicked in enough for me to parse it all. 😀
