* Fix issue to upgrade curator-recipes and related API.
* Resolve test failure: ClassNotFoundException of ZooKeeperAdmin.
* Remove unused property in pom.
* fix thread blocked problem of etcd watcher
in the previous version of EtcdDataSource, when the flowRules defined in the etcd change and trigger etcd watcher, there will be a following error:

I guess the reason is : when the watcher hold etcd Client, you can't use etcd Client in the Watch's consumer function.
Besides the problem above, use getKeyValue() in the watchEvent can reduce once invoke with etcd server to getting the latest flowRules :)
* Update EtcdDataSource.java
Add charset adaptation -- accept the suggestion from @LProDreamAll
* Add `@Spi` annotation as the general annotation for SPI definition.
* Add isDefault in @Spi, add loadDefaultInstance and improve loadFirstInstanceOrDefault method, improve test cases
* Add SpiLoaderException class for thrown when something goes wrong while loading Provider
* Rearrange packages of base SPI mechanism
NOTE: this PR contains breaking changes regarding API.
1. Added ARM64 architecture in .travis.yml
2. Updated 'embedded-consul' version to 2.2.0, 'consul-api' version to 1.4.5 for ARM64 support.
3. Updated grpc.version for 'io.grpc:protoc-gen-grpc-java' to 1.30.2, for ARM64 support.
