* improvement:check status of taskInstance from cache
* issue5572 use timer instead of while&sleep; consider concurrent modification
* use computeifpresent instead of lock
* simplify getByTaskInstanceId function
* add ut for TaskInstanceCacheManagerImpl; fix bug in TaskInstanceCacheManagerImpl
* add Apache license header;add test class in root pom
[Feature#3961]Registry SPI
All the logical structure of the registry must be converted into a tree structure within the system, so some plug-ins must be converted internally, such as ETCD
The registry supports distributed locks.
todo: The specific information about the registration center of the API module needs to be adjusted.
