WL#8315: Make innodb_checksum_algorithm=CRC32 the default in 5.7

Status: Complete   —   Priority: Medium

This work changes the default of innodb_checksum_algorithm to "CRC32" (was: innodb).

This gives better performance due to commonly available hardware acceleration.

Not required.
Only change the default from "innodb" to "crc32", nothing more should be necessary.
