Add an attribute which suppress the source appending

Fix #288

I added an boolean attribute named suppressSource which removes the source added to the command

Thank you a lot @jplayout for the PR.
I am facing the same issue on other "resources" such as "aws/ami" and I am wondering if it wouldn't be better to have something generic at the condition and at target level such as (not at the spec level like you are suggesting).

I am thinking of something like:

conditions:
    condition:
        disableSourceInput: true (default to false)
        kind: shell
        spec:
            command: xxx

And we could just have a condition that test if disableSourceInput is set to true then we set the source to an empty string
here

@olblak WDYT about merging this PR (eventually adapting the attribute name) to target a delivery for the 0.8.2 milestone, and then work on the 0.9.0 with a change like yours? Because an issue has to be written to think about the meaning of "source input" with your thoughts at least on the issue?

The reason is because we tagged the issue #288 to be first good issue, and we are exteding the scope now that the PR is open... ;)

Thats weird: I never clicked the merge button, neither did I enable the auto-merge 😕
Sorry for the inconvenience @olblak : don't hesitate to revert and a PR would be re-opened then

weird that the pr got merged anyway you made a good suggestion, I need to think a little bit about my suggestion and both are not incompatible. So let's move forward. I would just target a new minor version instead of a patch version
