Problem Description

Plugins are given the possibility to provide a plugin:install command. This command is run automatically when the first time a plugin is enabled for a tenant.

This behaviour leads to a couple on inconveniences

• Users have to option to re-run these initialisation commands, for example when new changes or fixes have been added
• The check for "first time" is very obscure, i.e. if (!$this->pluginsService->getByMpmPluginId($mpmPluginId) instanceof Plugins)
• Painful developer experience as this leads to the need to reset the development demo data quite frequently.

Proposed Solution

Please change the behaviour to

• Run package:install every time a plugin is enabled for a tenant

For this to work (apart from the obvious changes to the Plugin Service logic) a few steps have to be taken.

• Review each each Plugin's install command to make them idempotent, i.e. it should be save to run the install multiple times.
• Ensure Manufacturer registration is also idempotent

For example, an install command that creates default credentials using ->create() should be changed to ->firstOrCreate()
