Use 'vault kv put' instead of 'vault write'

When using vault_cli with a kv2 path, it isn't working. I have the following error:
```

The new way to write data  is to use `vault kv put`, it is compatible with kv1 and kv2.

```
The original version of K/V used the common read and write operations. A more advanced K/V Version 2 engine was released in Vault 0.10 and introduced the kv get and kv put commands.
