Can explicit script loading apis be supported

[dernayider]

When using spring-data-redis to execute Aerospike Lua scripts, an exception occurred during an evalsha call: redis.clients.jedis.exceptions.JedisNoScriptException: NOSCRIPT No matching script. Please use EVAL. The encapsulated RedisTemplate does not provide an API for executing loadScript, which prevents pre-loading the script into the Redis server. This leads to the NOSCRIPT error when using evalsha for script execution.

RedisScriptingCommands provides access to script commands on the RedisConnection-level. The template intentionally doesn't expose such methods as we provide a ScriptExecutor abstraction as frontend to run scripts.

A full stacktrace or reproducer would be helpful for further insights.
