…sting by replacing redis-rdb-tool with rdb-cli (sonic-net#1391)

Why I did it
Fix issue: sonic-net#1387
The latest redis-rdb-tools-0.1.15 doesn't support Redis 7.0. Redis 7.0 was released in 2020 and adopted by SONiC's latest version. So, this issue turned out.

I.e., the rdb-tools is far behind the Redis 7.0. The librdb can perfectly fix this issue. Please see quote from https://github.com/redis/librdb.

Motivation behind this project
There is a genuine need by the Redis community for a versatile RDB file parser that can export data, perform data analysis, or merely extract raw data from RDB and RESTORE it against a live Redis server. However, available parsers have shortcomings in some aspects such as lack of long-term support, lagging far behind the latest Redis release, and usually not being optimized for memory, performance, or high-traffic streaming for production environments. Additionally, most of them are not written in C, which limits the reuse of Redis components and the potential to contribute back to Redis repo. To address these issues, it is worthwhile to develop a new parser with a modern architecture, that maybe can also challenge the current integrated RDB parser of Redis and even replace it in the future.

So, the below PRS are to replace rdbtools with librdb's tool rdb-cli.
