[Enhancement]: Improve fluvio topic describe with additional information

[ajhunyady]

The current fluvio topic describe has been built 3 years ago and it's stale.

We should update this command with the following information:

$ fluvio topic describe my-topic
Name         : my-topic
Replication  : 1
Partitions   : 2 

PARTITION    LAST-OFFSET    LAST-PRODUCED   CONSUMERS
0            3,543          1 sec ago       c1, c2
1            1,240          5 sec ago       c3

Note

• Get offset and timestamp (for last produced) from fluvio partition list
• Get consumers from fluvio consumer list
