dfx identity info

[hansl]

Would show more information about the identity, such as:

name: default
principal: abcde-aa
path: /Users/hansl/.config/dfx/identity/default/identity.pem

Could also have a --json file for making this easier to script.

'info' isn't a verb, and it's not a very useful noun. dfx identity or dfx identity show could be more in line with the 'noun-verb' pattern we talked about a few arch meetings ago.

wrt --json, I think we already use that somewhere so it's fine sugar, but I wonder if --output json is more scalable, e.g. to --output yaml. This is what kubectl does and works well, e.g. kubectl get service foo -o json | jq .. They also have a way of doing jq-like things with -o jsonpath without needing to bring-your-own jq. https://kubernetes.io/docs/reference/kubectl/cheatsheet/#formatting-output
