[fix][cli] Fix Pulsar-Client CLI to print metadata of message including encryption metadata

[rdhabalia]

Motivation

Currently, client-cli doesn't print encryption related metadata which requires in my cases by users to troubleshoot encryption/decryption related issues and validate key related metadata.

Modifications

Add --print-metadata param in client-cli for consumer to allow to print additional metadata of the message.
