Forest plots of multivariate variables currently prepend the variable name to each element label, which adds a lot of clutter to the plot. This removes the variable names from all but the first element.

Can add this feature to other plots as needed, either here or in a separate PR.

Not sure what sort of test would be relevant here, if any.

Closes #1524

This looks great, thanks @fonnesbeck ! I don't think we need this for more plots -- or maybe plot_parallel ? Curious what the others think.
The test failure is weird, looks like a problem with Azure

How does this look in the case were there are no verbose coords?

@ahartikainen if the variable is not a multivariate random variable, then it uses the variable name. The only change should be in the multivariate case.

@AlexAndorra yes, they look like resource provisioning errors.

Actually, I noticed a bug with multiple non-combined chains:

OK, fixed. A multi-trace multivariate forest plot now looks like this:

whereas a forest plot of three univariate variables looks like this:
