[Maps] Allow features on a map to be text, as well as circles or icons

[richardachin18]

Currenty, you can plot features on a map as circles or a maki icon. Would be great to be able to plot it as text taken from a field. This applis to all mapping visualisations, though for my use case I am using elastic maps.

My use case is where I want to plot the health of HW devices around the US (600+ points). I plot these on the map as red or green, depending on whether device is functioning correctly or not. But rather than a circle (or preferably as well as), I would like to put the ID of the device. This consists of 4 letters, eg 'WXYZ', and is in a separate field.

Discussion coming from this forum thread. @thomasneirynck I haven't found any related issue to this topic but happy to close this one if we already captured this requirement elsewhere, and continue there.

This is the sort of how it could look like (extract here showing California). Key thing is the text above the circles is data driven from a field.

@nreese - your update for this feature looks great. Is there an easy way I can try it out, such as nightly build of kibana? Any idea when it would get into a release build? Thanks.

@richardachin18 you can try out the feature by running from source on Master branch. Follow the instructions at https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md#setting-up-your-development-environment.

The feature was backported to 7.x branch. This means that when the next release, 7.6, is branched from 7.x, it will contain the changes. To gain insight into release timing, you can look at the time deltas between branch creation and public release dates for prior minors 7.0 through 7.5
