Document persistent memory support

    Description

      Request:

      Can we have persistent memory support documented in 10.5 release notes? And somewhere in the documentation. I suspect it should be a separate article, mostly to explain pmem configuration.

      To make use of persistent memory the server has to be compiled with cmake -DWITH_PMEM=ON, it requires libpmem library installed.
      Only InnoDB redo log supports pmem. It uses different IO method (mmap-ed) on pmem, which results in better performance. One should point InnoDB redo log to pmem with --innodb-log-group-home-dir=/path/to/pmem/filesystem.

      pmem support was released along with 10.5.2
