      Description

      https://github.com/percona/percona-server/pull/4136

      1. Deprecate MyRocks variables `strict_collation_check` and `strict_collation_exceptions`. All collations are now supported for `CHAR` and `VARCHAR` indexed columns.

      2. Add a new variable "rocksdb_max_compaction_history":

         :dyn: Yes
         :scope: Global
         :vartype: Unsigned Integer
         :default: 64
      min = 0,
      max= UINT64_MAX
      Track history for at most this many completed compactions. The history is in the INFORMATION_SCHEMA.ROCKSDB_COMPACTION_HISTORY table.
