type [ `Fatal of string | `Recoverable of string ]
The “imposed” error types for “long-running” plugins.
A `Fatal _ error will make the target die with the error,
whereas if an error is `Recoverable _ Ketrew will keep trying
(for example, a networking error which may not happen later).

[ `Command_execution | `Connectivity | `Local_system ]
Get a glance at the gravity of the situation:
`Local_system: a function of the kind Unix.exec failed.`Connectivity: Host_io failed to run something but it does not
mean that the actual command is wrong; connectivity can be
restored later.`Command_execution: the system and networking did their job
but the particular command failed.
