Visdom: [Feature Request] Be able to retrieve list of all envs on server

[sbaio]

Hi !

Can we have a function (vis.all_envs) to retrieve all envs on server in order to filter environments by name/id ?

Thank you

This was implemented in #463

Hi, I was looking for env list too. I run
pip install --upgrade git+https://github.com/facebookresearch/visdom.git
and then

viz.get_env_list()

Traceback (most recent call last):

Sorry, I forgot to kill other (old) visdom servers, running on my system with different ports and permissions. Now it works fine.
