MDEV-20672 Inconsistent usage message for innodb_compression_algorithm
The usage message for the innodb_compression_algorithm system variable
did not list snappy, which was added as an optional compression algorithm
in MariaDB 10.1.3 and might actually work since
commit 90c52e5291b3ad0935df7da56ec0fcbf530733b4 (MDEV-12615)
in MariaDB 10.1.24.
Unfortunately, we will include also unavailable compression algorithms
in the list, because ENUM parameters allow numeric values, and we do
not want innodb_compression_algorithm=3 to change meaning depending on
the way how the source code was compiled.
