vault_generic_secret should be renamed to vault_generic

[chrismatteson]

It works perfectly fine for non "secret" resources. For instance I can manage azure auth config with it:

resource "vault_generic_secret" "example" {
path = "auth/azure/config"

data_json = <<EOT
{
"client_id": "",
"environment": "AzurePublicCloud",
"resource": "https://vault.hashicorp.com",
"tenant_id": "11111111-2222-3333-4444-55555555555"
}
EOT
}
