Error handling for MySQL plugin on entity field of data type `MultiSelectOptionSet`

[abrl91]

Feature description

The MySQL Prisma provider is not supporting an array of primitives. The error handling should be handled on thedb-mysql plugin. https://github.com/amplication/plugins/tree/master/plugins/db-mysql

The plugin should handle one of the main events (e.g. beforeCreateServer) and if needed the plugin will:

1. write the error message to the logger
2. throw and error? or "skip" the entire process
