An execution anti-condition; the condition defines when a target is
ready and therefore should be run if the condition is met:
- with
`Never the target always runs (because never “ready”),
- with
`Satisfied the target never runs (a bit useless),
- with
`Volume_exists v the target runs if the volume does not exist
(make-like behavior).
- with
`Volume_size_bigger_than (v, sz) Ketrew will get the total size
of the volume (in bytes) and check that it is bigger.
- with
`Command_returns (c, v) Ketrew will run the Ketrew_target.Command.t and
check its return value.
`And list_of_conditions is a conjunction of conditions.
