Bug #21235226 : THE --ENABLE-CLEARTEXT-PLUGIN IS NOT

                IMPLEMENTED IN ALL CLIENT PROGRAMS

Description: Option "enable-cleartext-plugin" is not
available for the following client utilities:-
mysqldump
mysqlimport
mysqlshow
mysqlcheck

Analysis: The unavailability of this option limits the
features like PAM authentication from using the above
mentioned utilities.

Fix: Option "enable-cleartext-plugin" is implemented in the
above mentioned client utilities.
