Commit Message: Split huge monolith mock header to speed up test compilation
Additional Description: `cluster_manager_test` only used a simple mock class `MockAdmin` from `test/mocks/server/mocks.h`, which is a huge mock library. After splitting, the overall build time for `cluster_manager_test` reduced from 143.481s to 82.443s in my build cluster.

Risk Level: low
Testing: existing tests
Docs Changes: N/A
Release Notes: no
Related Issues: envoyproxy#10917
