DUMP Command Not Supported in Garnet

[michel-archambault-SSDC]

Describe the bug

I have a simple C# program that do a db.KeyDump(key), but I get an exception when connected to a Garnet server (instead of a Redis server). The exception message is "ERR unknown command".

Steps to reproduce the bug

Example of code:

Console.WriteLine("Connecting to \"{0}\" using port \"{1}\"...", _redisHost, _redisPort);

ConnectionMultiplexer connection = ConnectionMultiplexer.Connect(_redisHost + ":" + _redisPort);
IDatabase db = connection.GetDatabase();

SortedSet<string> allKeys = new SortedSet<string>();
int scanCursor = 0;
do
{
    RedisResult[] result = (RedisResult[])db.Execute("SCAN", new object[] { scanCursor.ToString() });
    scanCursor = Int32.Parse(result[0].ToString());
    foreach (string key in (string[])result[1])
    {
        allKeys.Add(key);
    }
} while (scanCursor != 0);


foreach (string key in allKeys)
{
    _keyValueDict[key] = db.KeyDump(key);
}

Expected behavior

KeyDump() working.

DUMP is not implemented in Garnet.

I hope it will be implemented one day.

Because replication is not supported, this is must need function for copy/move data from redis/keydb/dragonfly to garnet (for validation)
