Add support for defining tags in Bru files

Add a generic `list` block to Bru grammar that holds simple text values
in square brackets separated by newlines.

Example usage:

```
meta {
  name: Login
  type: http
  seq: 1
}

tags [
  smoke-test
  authentication
]

post {
  url: https://example.com/login
  body: json
}
```
