Description

Yarn Federation contains some basic objects, which are listed below:

SubClusterId
SubClusterIdInfo
SubClusterInfo
SubClusterPolicyConfiguration
ApplicationHomeSubCluster
ReservationHomeSubCluster
RouterMasterKey
RouterStoreToken

The basic methods of these objects are not perfect, some lack equals, hashCode(), and some lack toString(). This pr will improve this part of the code.
