Mandatory versus optional artefacts

[joshliberty]

It should be possible to define whether input artefacts are mandatory or optional. If mandatory artefacts are missing the task shouldn't be executed, and an error should be logged instead.

This has been done as part of #52

[joshliberty]

@jackschofield23 if this was done, how do you specify per artifact whether it's mandatory or not?

[mocsharp]

@jackschofield23 is this done? can we close if so?
