Display number of messages & size in topic list
### Describe the solution you'd like

Display columns Number of messages & size in topic list page

Number of messages could be calculated from partitions:
backend provide list of partitions with min/max offset, 
number of messages = sum(partition max offset - partition min offset)
size - field segmentSize (it's in bytes, let's display it KB/MB/GB...)
