Migrate Teleporter example contracts from ava-labs/teleporter

[cam-schultz]

teleporter hosts a number of example applications built on top of Teleporter. We should migrate them to avalanche-starter-kit so that developers can more easily interact with them and modify them in the integrated development environment provided here.

See the corresponding teleporter issue here: ava-labs/teleporter#381

The examples have associated end-to-end tests, which are written in Go with Ginkgo. The Go/The Ginkgo infrastructure should be added to this repo before migrating the examples, so that the tests can come along too.

• Add Ginkgo E2E test support for Teleporter examples #4
• Migrate the tests
