Widget: OSM Data

[homersimpsons]

Is your feature request related to a problem? Please describe.
Some tasks are focused on editing or adding a given tag. Currently a user have some "slow" options:

• Open the editor
• Click "View OSM" in History Widget
• Toggle the OSM Data layer and click his feature (which is a bit buggy Do not reset map layers on task change. #2451 and Click on node osm data sometimes does not show the correct feature. #2452)

Describe the solution you'd like
Add a new widget "OSM DATA" that would display the tags and their values.

The widget would not allow tag edition. It will work about the same as the "osm history" widget.

Describe alternatives you've considered
Include this in the existing "osm history" widget:

• To me a user may need one but not the other

Use the "Custom URL" widget:

• I couldn't figure out how to make it work
• The osm page for a node is too verbose do be displayed concisely

Stick with the above 3 solutions:

• They involve multiple steps

Additional context
I may try to implement this widget using the "OSM History" widget as reference. I do not know when I will have availabilities to work on this hence I create an issue for anyone to pick up and to open the debate.
