Public Jenkins,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#9).

Change subject: IMPALA-9109: Add top-k metadata loading ranking on catalogd UI

IMPALA-9109: Add top-k metadata loading ranking on catalogd UI

Add functions in CatalogUsageMonitor to monitor and report the
catalog usage of the tables have the longest metadata loading
time(Including maximum, median, 75th-ile, 95th-ile, 99th-ile time).
Set default tables loading metrics capacity to 100.

However, there might be a problem here because we only keep the
capacity size to 100. For example, there might be case like a
table has higher median loading time but has lower Maximum
loading time which cannot make itself to the Top-100. For now,
we will ignore case like that because we are aiming to find
the tables with maximum longest loading time.

Add the sorted table in Catalog server web-ui. The loading
time is sorted by the maximum from load_duration metrics. But
users can sort by other metrics in catalogd debug UI.

Testing:
- Add end-to-end test for webpage to verify the label and text
exist in catalog debug page. Verify all fields are in JSON response
- Launch Impala and activate some tables to see the table loading
time shown successfully on the catalog debug UI page.
