feat(config): add rocksdb.wal_compression to allow enable wal compression

issue: #2606

add rocksdb.wal_compression to allow enable wal compression
only zstd supported, so field YesOrNo

[PragmaTwice]

I think it can be none and zstd instead of no and yes to leave some upgrading space.

By the way, may I ask that is this only for write-heavy workload(maybe with long and compress-able key-values)?

i have a lot key-value (uncompressed size in [256B, 8kB]) with good compression rate (value is json, where sum length of json's keys is bigger then json's values).
i have ~100-200MB/s write, wal and compaction load, so on aws i need use aws ec2 instances with enough cpu (see ec2 instance throughput limits https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-optimized.html).

finally i have a lot of free cpu. this pull request can help me decrease write load on disk and i can pickup cheaper ec2

I see, this make sense
