--------------------------------
Summary: list of masters in "/dump-entites" endpoint
Key: KUDU-3519
URL: https://issues.apache.org/jira/browse/KUDU-3519
Project: Kudu
Issue Type: Improvement
Reporter: Gabor Zele
I'm gathering all kudu metrics for analytics by using the "/metrics" endpoins
on all master/tablet servers. I'm getting the list of tablet-servers by
querying "/dump-entites" on a master server.
"/dump-entites" has top level key for "tablet_servers", but it doesn't contain
any information about the other masters. For this, I have to maintain a list of
master http adresses and server UUIDs in my solution, and update it there are
changes to the masters.
If the information would be available here, knowing the http address of any
working master would give me the list of configured masters, which I could
contact for metrics and save for future use.

This Jira is a request to add a key like "master_servers" to the
"/dump-entites" endpoint with the information about the other masters, like we
have now in "tablet_servers" for the tablet servers.
