Add HashiCorp Nomad provider (#483)
* provider: adding Nomad provider * updating CONTRIBUTING.md with Nomad provider * updated README.md by adding the Nomad provider * fix typo * adding nomad/api and nomad/testutil deps * adding Nomad binary dependency for provider tests * fixed the nomad binary download command step and added tolerations to the nomad provider. * adding nomad provider demo gif * adding my name to authors * adding two missing go-rootcerts files after dep ensure * delete pod comment
