Rudder

When doing a minor upgrade of the server, all plugins are disabled before the upgrade and not re-enabled afterward.
This is very misleading for the users.
It displays the following error message:

********************************************************************************
Due to incompatibility reasons for this specific version all plugins have been
disabled. Make sure to update your repo index and install the latest version of
your plugins before re-enabling them.

You can use the following commands to upgrade your plugins:
rudder package update
rudder package upgrade-all
********************************************************************************

But running the given commands will not solve anything when applying a minor update.
It will only work on major ones.

It happens when upgrading from 6.0.6 to 6.0.8-nightly

But the plugins should not be changed in a minor update. I think this is an unclean workaround when we broke plugin compatibility in 6.0.4.
We should most likely either:

• State than an upgrade disabled all plugins and let the user re-enabled them manually
• Save the plugin state before update and try to re-enable them. This need to differentiate the minor upgrades from the major ones.
