1. storage: add storage.sstable.compression_algorithm cluster setting …

   Introduce a new cluster setting that allows the operator to configure the
   compression algorithm used when compressing sstable blocks. This allows
   operators to opt into use of zstd (as opposed to the previous setting of
   snappy). ZSTD typically achieves better compression ratios than snappy, and
   operators may find that they can achieve higher node densities through enabling
   zstd. Future releases may change the default compression algorithm.
   
   In a side-by-side comparison of a 10000-warehouse tpcc import, the zstd cluster
   achieved a higher import speed of 146 MiB/s versus snappy's 135 MiB/s. The zstd
   cluster's physical database size was significantly less.
   
   Epic: none
   Release note (ops change): Add `storage.sstable.compression_algorithm` cluster
   setting that configures the compression algorithm to use when compressing
   sstable blocks.
