hack/ci/setup-build-dependencies.sh: add setup script in SDK repo

[joelanford]

Description of the change:
Adds a setup script that can be used in OpenShift CI

Motivation for the change:
We currently hard-code the dep setup commands in the openshift/release repo.

Once this script is merged into master, we can update the OpenShift CI configuration to use it, which then gives us the flexibility to change the test setup from the SDK repo, rather than having to make coordinating changes in openshift/release.

This will be helpful in migrating the SDK from using dep to go modules (see #1566)

lgtm 👍

Any reasons why we are using 0.5.0 and not latest 0.5.4 release?

[joelanford]

@lilic Probably just because the original command hasn't been updated in awhile. I'll bump the version.

To test it you can try to bump it in our .travis.yaml to see if we run into any problems. I wanted to suggest calling this script there, but since we are moving away from travis doesn't make much sense I guess.

@lilic I bumped to v0.5.3. Looks like v0.5.4 isn't quite released or something. There are no binaries on the dep release page for it.

I also updated .travis.yml so we can make sure it still works. I also thought about using this script in .travis.yml, but we also do things slightly different there (e.g. use travis_retry dep ensure -v instead of make dep)

@joelanford yes noticed that as well, not sure what happened in that "release".

Still lgtm on green of course 👍
