Add byte-level progress to pgcopydb list progress

[marcocitus]

It would be useful if pgcopydb list progress would give more detailed information such as the number of bytes copied and maybe information from pg_stat_progress_create_index.

Required metrics to be exposed:

• Table & Index Copy Process Count
• Count of tables which will be copied parallelly based on threshold
• Data transfer speed (bytes transferred) (time series)

Editors note: @marikkan-microsoft please do not include screenshot of a block of text. It is not accessible.

Closing for triage purposes. The initial issue created one year ago has been fixed now. The additional elements added two weeks ago should probably be separate issues/enhancement ideas.
