Change subject: IMPALA-6663 Expose current DDL metrics on WebUI
......................................................................


Patch Set 7:

Hi Vihang, thank your for the review.

These metrics could be useful to identify if the CatalogD starts to become the 
bottleneck, for example when the metadata operations start piling up due to 
IMPALA-6671. Although, this change will not help to identify which tables are 
causing problem, it could give the user an idea on how busy/stuck the CatalogD. 
To have further understanding on the load I believe we would need historical 
data.

Displaying the table names could be a useful addition, will add a third column 
to this patch.

What do you think?
