Kibana: [canvas] Improve copy of "Add from Visualize library" button to be more inclusive for non-visualize library embeddables

[nreese]

Canvas add embeddable button currently has the copy "Add from Visualize library". This language is very specific and does not convey all of the functionality. For example, while looking to add map, I was confused by this text and did not realize this was the add embeddable button.

I recommend changing the button copy to something more generic so its inclusive to non-visualize library embeddable like maps. Dashboard uses the phrase "Add panel". How about "Add Kibana panel"?

@ryankeairns @crob611 ...do you guys have an opinion on this in the short term?

Perhaps "Add from Kibana" or "Add from Library"...?

@nreese Canvas "Time to Present" is making some changes here in the 7.x timeframe, so this is an excellent point to consider moving forward... thanks!

++ to "Add from Kibana"

Would a combination of the two work?

Add from Kibana library
