Subject: [PATCH] RESP3: Lua parsing should depend on lua client, not lua
 caller.

We want all the scripts to run in RESP2 mode by default. It's up to the
caller to switch to V3 using redis.setresp() if it is really needed.
This way most scripts written for past Redis versions will continue to
work with Redis >= 6 even if the client is in RESP3 mode.
