Add RM_SetContextUser to support acl validation in RM_Call (and scripts) (#10966)
Adds a number of user management/ACL validaiton/command execution functions to improve a Redis module's ability to enforce ACLs correctly and easily. * RM_SetContextUser - sets a RedisModuleUser on the context, which RM_Call will use to both validate ACLs (if requested and set) as well as assign to the client so that scripts executed via RM_Call will have proper ACL validation. * RM_SetModuleUserACLString - Enables one to pass an entire ACL string, not just a single OP and have it applied to the user * RM_GetModuleUserACLString - returns a stringified version of the user's ACL (same format as dump and list). Contains an optimization to cache the stringified version until the underlying ACL is modified. * Slightly re-purpose the "C" flag to RM_Call from just being about ACL check before calling the command, to actually running the command with the right user, so that it also affects commands inside EVAL scripts. see #11231
