refactor: blind write method

fix: lint errors

fix: Retry with timeout (#2071)

Use `gaxOptions.timeout` during retry in streaming calls. Earlier the timeout value was only used for a single RPC not for the whole operation including retries. Now if RPC returns `Unavailable` error and the timeout value has been reached, library will throw an Deadline exceeded error.

```
const query = {
        sql: 'Select 1',
        gaxOptions: {timeout: 500}
    }
const [rows] = await database.run(query);
```
