Show workload identity information

[nrfox]

What do you want to improve?

Show information about a workload's identity. This can be helpful when trying to get more details around mTLS for a workload. This info exists in the envoy config dump but there's probably better ways of getting it.

What is the current behavior?

No way to see workload identity information.

What is the new behavior?

Show some workload identity information.

Wondering where this comes from in Ambient, with ztunnel.
