[Java Client][REQUIREMENT] Supported shared components

[gong-yu]

Is your feature request related to a problem? Please describe.
When using Singleton Java client, sometimes some strings/translations come from a third-party library which has also integrated with Singleton. In this case, the strings are stored in Singleton with 2 copies. It not only wastes storage but also introduces translation consistency issue.

Describe the solution you'd like
Singleton should support such scenario. Only one copy of strings should be collected and stored in Singleton Service.

Describe alternatives you've considered
