Add support to go-redis/v8

[minimAluminiumalism]

Ref #1053

This project currently does not support Redis. Instrumentation for the library github.com/go-redis/redis/v8 is quite complex, primarily because some of the available instrumentation functions include parameters of type interface{} (this issue is also mentioned in #1209) like this:

func (c *baseClient) process(ctx context.Context, cmd Cmder)

This PR implements support for go-redis/v8. In fact, since the key instrument functions in go-redis/v9 remain unchanged, support for v9 might also be possible in the future. The approach involves detecting the interface{} type, first determining the specific type, and then retrieving the corresponding value based on that type.

However, at the moment, only the standard mode of Redis is supported, and pipeline mode is not yet supported. Plans are in place to add support for pipeline mode in the future.
