Charlie Drage 43b1ca0fe0 Resolve logrus and gojsonschema vendoring conflicts
Some vendoring is blocking other PR's due to changes to logrus (Sirupsen
vs sirupsen for lower-case) as well as a non-versioned gojsonschema in
glide.yaml

This updates glide.yaml to reflect the upper-case as well as lower-case
versions of logrus as well as adds a versionized gojsonschema in order
to get rid of the following error:
