Allow adding variables to inventory(host file), available variables:

```text

```

Example host file:

```text
alias_name_node1 host=node1.sre.im
alias_name_node2 host=192.168.33.12 port=22 user=vagrant password=vagrant keys=~/.ssh/id_dsa,~/.ssh/id_rsa passphrase=xxx
node3.sre.im user=vagrant password=GOSSH-AES256:9cfe499133b69a6c7fc62b5b6ba72d3d8dfb4d0e7987170a40c5d50bb5d71e19
