[Feature] Support for cleaning the trash actively

[BiteTheDDDDt]

Is your feature request related to a problem? Please describe.
Sometimes, garbage data will accumulate and take up a lot of space, users who want to clean up trash can only delete files by themselves.

Describe the solution you'd like
Add a sql statement for cleaning the trash actively.
format:
admin clean trash;
admin clean trash on ("BackendHost1:BackendHeartBeatPort1", "BackendHost2:BackendHeartBeatPort2", ...);
