Add missing commands to UnifiedJedis

[uglide]

Add implementation for the:

• CLIENT commands
• CONFIG commands
• Various server commands like: dbsize, time, etc

---

Note

Medium Risk
Expands UnifiedJedis API surface and introduces cluster broadcast behavior for server/config commands, which can have correctness differences across nodes (some cases already require disabling/expecting failures in cluster tests). Mostly additive changes but touches core command plumbing and public interfaces.

Overview
Adds missing Redis command coverage to UnifiedJedis, including common server commands (ping w/ message, binary echo, flushAll/flushDB w/ FlushMode, lolwut, time, dbSize), plus full CONFIG and CLIENT command support.

Extends CommandObjects with the new command builders and wires UnifiedJedis to execute vs broadcast the new operations as appropriate; adds integration tests for client/config behavior in both standalone and cluster modes (with a few cluster-incompatible cases explicitly disabled/expected to throw).

Refactors the command API by splitting ServerCommands and DatabaseCommands into smaller sub-interfaces (e.g., CommonServerCommands, AuthCommands, ShutdownCommands, NodeDatabaseCommands, etc.) while keeping ServerCommands/DatabaseCommands as composite interfaces for backward compatibility.
