Add support for MySQL >=5.7.19 #177
Description
Currently this package only supports MySQL >=8.0.20. The work done in #176 adds support for this package to use MySQL >=8.0.11. With the changes made in #176, if you try to run an older version of MySQL, it fails because when running the MySQL binary we are adding the following command line options: mysqlx, mysqlx-port, and mysqlx-socket.
It seems like MySQL <8.0.11 do not have MySQL X enabled by default and that is causing the server to crash on start up as we are passing it unknown options. If we install the MySQL X Plugin then these options will no longer be unknown and we should be getting MySQL >=5.7.19 support.
