Review comment:
According to this
article:https://stackoverflow.com/questions/52054427/how-to-integrate-apache-airflow-with-slack/52054663
SlackWebhookOperator could be set like this:
```
from airflow.contrib.operators.slack_webhook_operator import
SlackWebhookOperator
slack_msg="Hi Wssup?"
slack_test = SlackWebhookOperator(
task_id='slack_test',
http_conn_id='slack_connection',
webhook_token='/1234/abcd',
message=slack_msg,
channel='#airflow_updates',
username='airflow_'+os.environ['ENVIRONMENT'],
icon_emoji=None,
link_names=False,
dag=dag)
```
And set the host of slack in connection like this:
`host=https://hooks.slack.com/services/`
The argument-`http_conn_id` will be used for getting the hostname of Slack.
But in current version, `http_conn_id` can't be passed the parent
class-`HTTPHOOK`, so that `HTTPHook` will read the host by the default
http_conn_id `http_default` and send the msg to
`https://www.google.com/YOUR_ENDPOINT`.
