Refactor proxy shard client management by creating a new
internal/proxy/shardclient package. This improves code organization and
modularity by:
- Moving load balancing logic (LookAsideBalancer, RoundRobinBalancer) to
shardclient package
- Extracting shard client manager and related interfaces into separate
package
- Relocating shard leader management and client lifecycle code
- Adding package documentation (README.md, OWNERS)
- Updating proxy code to use the new shardclient package interfaces
This change makes the shard client functionality more maintainable and
better encapsulated, reducing coupling in the proxy layer.

This commit refactors the privilege management system in the proxy
component by:
1. **Separation of Concerns**: Extracts privilege-related functionality
from MetaCache into a dedicated `internal/proxy/privilege` package,
improving code organization and maintainability.
2. **New Package Structure**: Creates `internal/proxy/privilege/` with:
- `cache.go`: Core privilege cache implementation (PrivilegeCache)
- `result_cache.go`: Privilege enforcement result caching
- `model.go`: Casbin model and policy enforcement functions
- `meta_cache_adapter.go`: Casbin adapter for MetaCache integration
- Corresponding test files and mock implementations
3. **MetaCache Simplification**: Removes privilege and credential
management methods from MetaCache interface and implementation:
- Removed: GetCredentialInfo, RemoveCredential, UpdateCredential
- Removed: GetPrivilegeInfo, GetUserRole, RefreshPolicyInfo,
InitPolicyInfo
- Deleted: meta_cache_adapter.go, privilege_cache.go and their tests
4. **Updated References**: Updates all callsites to use the new
privilegeCache global:
- Authentication interceptor now uses privilegeCache for password
verification
- Credential cache operations (InvalidateCredentialCache,
UpdateCredentialCache, UpdateCredential) now use privilegeCache
- Policy refresh operations (RefreshPolicyInfoCache) now use
privilegeCache
- Privilege interceptor uses new privilege.GetEnforcer() and privilege
result cache
5. **Improved API**: Renames cache functions for clarity:
- GetPrivilegeCache → GetResultCache
- SetPrivilegeCache → SetResultCache
- CleanPrivilegeCache → CleanResultCache
This refactoring makes the codebase more modular, separates privilege
management concerns from general metadata caching, and provides a
clearer API for privilege enforcement operations.
