Improve performance by using cached images our deployment definitions specify imagePullPolicy's of always

I notice that a ton of our deployment definitions specify imagePullPolicy's of always which basically invalidates the host cache for kind. What do we think about changing this? If I threw up a PR to change this to IfNotPresent would we be ok with that? Or do we think this needs to be user-settable?

This has already been fixed in this PR: #236

Will become available in the next release. Gotta make sure that we build the latest version of the embedded packages by running generate-manifest before cutting the release.
