Builds upon https://github.com/coder/coder/pull/19970
I got kinda carried away when I saw the extra stuff we could add in
here, so I went ahead and added it:
* User ID
* Organization IDs
* Roles
This technically duplicates functionality from `coder users show` but I
figure folks may find it useful.
This addresses a long-standing gripe of mine: to get your logged in
username you would have to do
```bash
coder whoami | awk '{print $9}'
```
This allows you to do:
```
coder whoami -o json | jq -r '.username'
```
or
```
coder whoami -f table -c username
```
Refactors the CLI to create the `*codersdk.Client` in the handlers. This is groundwork for changing the `rootCmd.InitClient()` to use the new `ClientOption`s.
It also improves variable locality, scoping the Client to the handler. This makes misuse less likely and reduces the memory allocations to just the command being executed, rather than allocating a Client for every command regardless of whether it is executed.
* feat: added whomai cmd to coder cli
* refactor: update Coder CLI's whoami command to use client URL instead of deployment config
* feat(cli): add unit tests for the whoami command
* chore(docs): add coder command to fetch authenticated user info
* chore(doc): update help desc
