    Description

      plugins should be able to provide install/uninstall/upgrade scriptlets (at least shell, perhaps sql too).

      they'll be called at the appropriate places by rpm/dpkg as needed.

      in bintars install scriptlets will be run by mysql_install_db and mysql_upgrade.

            Another option (as suggested in MDEV-19852) would be to run them on INSTALL/UNINSTALL PLUGIN.

            That might work if there's an SQL scriptlet to run. But it cannot do a shell scriptlet.

            shell scriptlets can be used by pam plugin to fix filesystem permissions

            running from rpm/deb:
            run when a plugin package (or a server package with a plugin) is installed
            run on upgrades too
            somewhat different code for rpms and debs
            bintar packages can only do it from mysql_install_db
            mysql_install_db doesn't handle upgrades. mysql_upgrade ?
            sql scriptlets need a running server
            Should a plugin be active when its sql scriptlet is run? or is a scriptlet a prerequisite for a plugin being able to start?

            running sql scriptlets by the server on INSTALL PLUGIN:
            uniform treatment for rpm/deb/bintar
            needs a new version column in mysql.plugin to detect upgrades
            doesn't support shell scriptlets (but it can run wsrep scripts, so why not?)
            --plugin-load is treated like installing on every server startup (up to the script to detect it?)
