[ML] Adding cloud trial end date to ml info (#144793)

Adds a `isCloudTrial` flag to ML's `/api/ml/info` endpoint.
If `xpack.cloud.trial_end_date` is set in the kibana config and it is
greater than the current time, we can assume that we're currently in a
could trial.
If `xpack.cloud.trial_end_date` is not set, `isCloudTrial` is not added
to the endpoint response. This is the same behaviour as the `cloudId`
property.

Adds a `isCloudTrial()` function to our server info util functions which
can be used in conjunction with our `isCloud()` function.

To test, these cloud settings can be added to the kibana config:
```
xpack.cloud.id: 'cloud_message_test:ZXUtd2VzdC0yLmF3cy5jbG91ZC5lcy5pbyQ4NWQ2NjZmMzM1MGM0NjllOGMzMjQyZDc2YTdmNDU5YyQxNmI1ZDM2ZGE1Mzk0YjlkYjIyZWJlNDk1OWY1OGQzMg=='
xpack.cloud.trial_end_date: '2022-11-20T09:39:52.554Z'
```
