Change node labels default alignment

[vincent0965]

Modification of the node default position in the settings has no effect

Sigma.js version: 2.3.0
Graphology version: 0.24.1
vue version: 2.6.14

My problem is that when I want to set label for nodes is on the bottom hand side or node inside, and I used to json file save nodes info.

I set defaultLabelAlignment:"bottom" and look at the code,but both its unavail, anything I am doing wrong?

Is it possible to move the label to others position of the node?

I decided to take the same decision as for #1357:

After having been thinking a lot on this issue, I decided to not implement it. Right now, sigma's APIs is made so that people who have advanced usecases should write their own label renderers. That's what we do in the demo for instance.

Also, labels rendering APIs might change in the near future (to handle #1319 for instance), so I don't want to commit more code/debt into it.
