ZOOKEEPER-3188: Improve resilience to network This PR is the rebase of the [previous pull request](https://github.com/apache/zookeeper/pull/730), so all the kudos should go to the original authors... In [ZOOKEEPER-3188](https://issues.apache.org/jira/browse/ZOOKEEPER-3188) we add ability to specify several addresses for quorum operations. Also added reconnection attempts if connection to leader lost. In this PR I rebased the changes on the current master, resolving some minor conflicts with: - [ZOOKEEPER-3296](https://issues.apache.org/jira/browse/ZOOKEEPER-3296): Explicitly closing the sslsocket when it failed handshake to prevent issue where peers cannot join quorum - [ZOOKEEPER-3320](https://issues.apache.org/jira/browse/ZOOKEEPER-3320): Leader election port stop listen when hostname unresolvable for some time - [ZOOKEEPER-3385](https://issues.apache.org/jira/browse/ZOOKEEPER-3385): Add admin command to display leader - [ZOOKEEPER-3386](https://issues.apache.org/jira/browse/ZOOKEEPER-3386): Add admin command to display voting view - [ZOOKEEPER-3398](https://issues.apache.org/jira/browse/ZOOKEEPER-3398): Learner.connectToLeader() may take too long to time-out I still want to test the feature manually (e.g. using docker containers with multiple virtual networks / interfaces). The steps to the manual test could be recorded in the [google docs](https://docs.google.com/document/d/1iGVwxeHp57qogwfdodCh9b32P2_kOQaJZ2GDo7j36fI/edit?usp=sharing) as well. Also I think we could add a few more unit tests where we are using multiple addresses. The current tests are using a single address only. Also the Zookeeper documentation needs to be changed (e.g. by a follow-up Jira?) to promote the new feature and the new config format (possibly including also the admin command documentation in relation with [ZOOKEEPER-3386](https://issues.apache.org/jira/browse/ZOOKEEPER-3386) and [ZOOKEEPER-3461](https://issues.apache.org/jira/browse/ZOOKEEPER-3461)) Author: Mate Szalay-Beko <szalay.beko.mate@gmail.com> Author: Mate Szalay-Beko <mszalay@cloudera.com> Reviewers: eolivelli@apache.org, andor@apache.org Closes #1048 from symat/ZOOKEEPER-3188 and squashes the following commits: 3c6fc52d7 [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 356882d46 [Mate Szalay-Beko] ZOOKEEPER-3188: document new configuration format for using multiple addresses 45b6c0fdb [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 4b6bcea48 [Mate Szalay-Beko] ZOOKEEPER-3188: MultiAddress unit tests for Quorum TLS and Kerberos/Digest authentication 40bc44c23 [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 f875f5c67 [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 31805e79b [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 0f95678ca [Mate Szalay-Beko] ZOOKEEPER-3188: skip unreachable addresses when Learner connects to Leader e232c55da [Mate Szalay-Beko] ZOOKEEPER-3188: fix flaky unit MultiAddress unit test e892d8d8e [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 6f2ab755f [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 2eedf2687 [Mate Szalay-Beko] ZOOKEEPER-3188: fix PR commits; handle case when Leader can not bind to port on startup 483d2fc9c [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 a5d6bcb97 [Mate Szalay-Beko] ZOOKEEPER-3188: support for dynamic reconfig + add more unit tests ed31d2ce9 [Mate Szalay-Beko] ZOOKEEPER-3188: better shutdown for executors (following PR comments) 8713a5bbf [Mate Szalay-Beko] ZOOKEEPER-3188: add fixes for PR comments 05eae83c0 [Mate Szalay-Beko] Merge remote-tracking branch 'apache/master' into ZOOKEEPER-3188 e823af4b1 [Mate Szalay-Beko] Merge remote-tracking branch 'origin/master' into ZOOKEEPER-3188 de7bad2a6 [Mate Szalay-Beko] Merge remote-tracking branch 'origin/master' into ZOOKEEPER-3188 da98a8da6 [Mate Szalay-Beko] ZOOKEEPER-3188: fix JDK-13 warning 5bd1f4e2c [Mate Szalay-Beko] ZOOKEEPER-3188: supress spotbugs warning 42a52a688 [Mate Szalay-Beko] ZOOKEEPER-3188: improve based on code review comments 6c4220a0d [Mate Szalay-Beko] ZOOKEEPER-3188: fix SendWorker.asyncValidateIfSocketIsStillReachable 5b22432c1 [Mate Szalay-Beko] ZOOKEEPER-3188: fix LeaderElection to work with multiple election addresses 7bfbe7e5c [Mate Szalay-Beko] ZOOKEEPER-3188: Improve resilience to network
