feat(*): enable parameters of type file in Porter manifest

[vdice]

Enables Porter manifest parameters of type file. Ref #480

TODO:

• remove vendor mods: PR changes to cnab-go and update Gopkg w/ temp commit, etc.... or something else entirely (see Parameter with valid JSON Schema definition may fail validation cnabio/cnab-go#117)

Note: validation broken pending #581

@vdice We are finally off of that one custom branch of cnab-go! 🎉 I think you are all set to rebase your cnab-go branch off of v0.4.0-beta1 and then we can reference your branch here and merge.

@carolynvs Oops, I rebased my cnab-go branch off of master as opposed to v0.4.0-beta1, but the only extra change appears to be:

--- a/vendor/github.com/deislabs/cnab-go/claim/claim.go

Still have the two comments/suggestions above to revisit...

master is fine, we just needed to not move backwards is all 👍

[carolynvs]

Just one small thing to fix and then we are good to go!
