The following operations comprise the method for enabling or disabling
a plugin. We begin by processing the command options then check the
directories specified for --datadir, --basedir, --plugin-dir, and
--plugin-ini (if specified). If the directories are Ok, we then look
for the mysqld executable and the plugin soname. Finally, we build a
bootstrap command file for use in bootstraping the server.
If any step fails, the method issues an error message and the tool exits.
1) Parse, execute, and verify command options.
2) Check access to directories.
3) Look for mysqld executable.
4) Look for the plugin.
5) Build a bootstrap file with commands to enable or disable plugin.
