vendor the sessions/sessiondb/badger database

//  The Iris' vendored badger it's self-vendored as well.
	// Why?
	// Because they were changing their public API a lot and iris was unable to built itself...
	// https://github.com/dgraph-io/badger/pull/256
	// https://github.com/dgraph-io/badger/pull/254
	// https://github.com/dgraph-io/badger/pull/261
	// I fixed everything by pushing a PR(the original's repository tests were failing) from the kataras/badger to the dgraph-io/badger:
	// https://github.com/dgraph-io/badger/pull/264
	// But it's better to have it on its own folder for the shake of stability,
	// Iris should be not affected of any third-party changes,
	// this method guards against upstream renames and deletes.
