Add support for scripting commands with Jedis Cluster [DATAREDIS-1005]

[spring-projects-issues]

Pavel Khokhlov opened DATAREDIS-1005 and commented

Current implementation of JedisClusterConnection doesn't support Eval & EvalSha commands
(see: https://redis.io/commands/eval, https://redis.io/commands/evalsha)

The reason is class:
org.springframework.data.redis.connection.jedis.JedisClusterScriptingCommands
do not have implementations of required commands:

@Override
public <T> T eval(byte[] script, ReturnType returnType, int numKeys, byte[]... keysAndArgs) {
   throw new InvalidDataAccessApiUsageException("Eval is not supported in cluster environment.");
}

@Override
public <T> T evalSha(String scriptSha, ReturnType returnType, int numKeys, byte[]... keysAndArgs) {
   throw new InvalidDataAccessApiUsageException("EvalSha is not supported in cluster environment.");
}

Eval & EvalSha commands has to be implemented.

For now we have an exception:

org.springframework.dao.InvalidDataAccessApiUsageException: EvalSha is not supported in cluster environment.
