WL12475 provides a framework to configure compression algorithm and compression
level to be used with mysql protocol. Different compression algorithms
supported for mysql protocol compression are zlib and zstd.

MYSQL_OPT_COMPRESSION_ALGORITHMS option can be used to configure compression
algorithm from a client application. MYSQL_OPT_ZSTD_COMPRESSION_LEVEL option
can be used to specify compression level for zstd compression algorithm.

This WL also introduces a new server variable "protocol-compression-algorithms"
which can be used to configure servers compression algorithms. Based on how
this variable is configured mysql protocol compression algorithm is negotiated
between client and server accordingly.

This WL also extends CHANGE MASTER TO statement to allow users to configure
compression algorithm/level on slave replication channels. To view what
compression algorithm and compression level are configured on a connection
user can query status variables like compression_algorithm and compression_level.
