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:

+// Go-toml can operate on a TOML document as a tree. Use one of the Load*
-//   tree, err := toml.Load(stringContainingTomlData)
+// functions to parse TOML data and obtain a Tree instance, then one of its
-//
+// methods to manipulate the tree.
-// Either way, the result is a Tree object that can be used to navigate the
-// structure and data within the original document.
-//
-//
-// Getting data from the Tree
-//
-// After parsing TOML data with Load() or LoadFile(), use the Has() and Get()
-// methods on the returned Tree, to find your way through the document data.
-//
-//   if tree.Has("foo") {
-//     fmt.Println("foo is:", tree.Get("foo"))
-//   }
-//
-// Working with Paths
-//
-// Go-toml has support for basic dot-separated key paths on the Has(), Get(), Set()
-// and GetDefault() methods.  These are the same kind of key paths used within the
-// TOML specification for struct tames.
-//
-//   // looks for a key named 'baz', within struct 'bar', within struct 'foo'
-//   tree.Has("foo.bar.baz")
-//
-//   // returns the key at this path, if it is there
-//   tree.Get("foo.bar.baz")
-//
-// TOML allows keys to contain '.', which can cause this syntax to be problematic
-// for some documents.  In such cases, use the GetPath(), HasPath(), and SetPath(),
-// methods to explicitly define the path.  This form is also faster, since
-// it avoids having to parse the passed key for '.' delimiters.
-//
-//   // looks for a key named 'baz', within struct 'bar', within struct 'foo'
-//   tree.HasPath([]string{"foo","bar","baz"})
-//
-//   // returns the key at this path, if it is there
-//   tree.GetPath([]string{"foo","bar","baz"})
-//
-// Note that this is distinct from the heavyweight query syntax supported by
-// Tree.Query() and the Query() struct (see below).
-//
-// Position Support
-//
-// Each element within the Tree is stored with position metadata, which is
-// invaluable for providing semantic feedback to a user.  This helps in
-// situations where the TOML file parses correctly, but contains data that is
-// not correct for the application.  In such cases, an error message can be
-// generated that indicates the problem line and column number in the source
-// TOML document.
-//
-//   // load TOML data
-//   tree, _ := toml.Load("filename.toml")

-//   // get an entry and report an error if it's the wrong type
