add scaleway_user_data resource

[nicolai86]

this PR adds a scaleway_user_data resource to manage server specific user data.

Example usage:

resource "scaleway_server" "base" {
  name = "test"
  # ubuntu 14.04
  image = "5faef9cd-ea9b-4a63-9171-9e26bec03dbc"
  type = "C1"
  state = "stopped"

  user_data {
   key = "gcp_password"
   value = "supersupersecret"
  }
}

resource "scaleway_user_data" "gcp" {
  server = "${scaleway_server.base.id}"
  key = "gcp_username"
  value = "supersecret"
}

In this example two user data objects are being created: one, inline in the scaleway_server resource, and one as a separate resource.
Both user data objects can be accessed from the server. For more details see the user data documentation from scaleway.

test are green:

# make testacc TESTARGS="-ru
n='TestAccScalewayUserData_Basic'"

TF_ACC=1 go test $(go list ./... |grep -v 'vendor') -v -run='TestAccScalewayUserData_Basic' -timeout 120m

@tombuildsstuff I've updated the PR slightly to also include inline user_data attributes as part of the scaleway_server resource. Let me know what you think.

Pulling this in optimistically - if additional adjustments are needed I’ll CR them separatly
