Add a "Current time marker" feature to new charts

[gospodarsky]

Like in the issue elastic/kibana#26459 it would be nice to know that new charts have an opportunity to display a marker with current timestamp between the past and the near future.

Like this:

Kibana Cross Issues
elastic/kibana#26459

@Avinar-24 thanks for the request. I think you can already achieve this using an Annotations, we just delivered yesterday this feature and it's available starting from 3.6.0 #126

@emmacunningham could you check if it's possible to disable the tooltip, because I don't think we have any tooltip when hovering over the time marker in vislib

[emmacunningham]

@Avinar-24 With the merge of #154, you should now be able to disable the tooltip hover state by adding hideTooltips={true} to the LineAnnotation spec, so that the annotation for the current time will not show anything on hover.

@Avinar-24 please close this issue if release 3.8.0 solve your request

[gospodarsky]

@emmacunningham, @markov00 Thanks for updates. I'll check the issue as soon as the 3.8.0 is merged to TSVB. elastic/kibana#33558

[markov00]

@Avinar-24 any news about that?

[gospodarsky]

@markov00 The issue depends on elastic/kibana#33558 and that issue also depends on the charts roadmap. But as I see new version of charts has been delivered with necessary functionality and it must speed the progress up. Updates will come soon. Thanks.

Closing as this is achievable with a LineAnnotation as written here #150 (comment)
