Future: dfx identity list - see principals

[infu]

The command dfx identity list could be improved slightly

Current output:
identity1
identity2
identity3
identity4
identity5

Requested output (Table containing the principals of each identity. Perhaps even cycle balances):

identity1 | principal | wallet principal
identity2 | principal | wallet principal
identity3 | principal | wallet principal
...

I actually do this often enough that I have a script to do this. :-)

I prefer JSON output when programming but that could be an option. E.g. there could be dfx identity list --format=json or similar.

I do have in mind that if dfx ever gets address book functionality, this should probably be consistent with the address book output. I have a home-baked address book with commands such as whois (looks up a principal in my address book) and whocontrols (gets the principals controlling a canister and looks them all up in my address book).

The list of fields provided could be variable. E.g. the gh cli supports a list of fields:

$ gh pr list --json
Specify one or more comma-separated fields for `--json`:
  additions
  assignees
  author
  autoMergeRequest
  baseRefName
...
$ gh pr list --json url,title
[
  {
    "title": "redacted",
    "url": "https://github.com/redacted"
  },
  ...

That way the command could start with offering just identity name and principal, for example, and add more values gradually. No-longer supported fields can also be dropped in a graceful manner.
