### Description of PR
Currently, RouterObserverReadProxyProvider is using IPFailoverProxyProvider,
while ObserverReadProxyProvider is using ConfiguredFailoverProxyProvider. If
we are to align RouterObserverReadProxyProvider with ObserverReadProxyProvider,
RouterObserverReadProxyProvider should internally use
ConfiguredFailoverProxyProvider. Moreover, IPFailoverProxyProvider has an
issue with resolving HA configurations. (For example, IPFailoverProxyProvider
cannot resolve hdfs://router-service.)
### How was this patch tested?
`mvn test -Dtest=TestObserverWithRouter` succeeded in my local computer.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [x] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
