When clowder running on a closed intranet, API link need to be change to local url.

[gitdiving]

When clowder running on a closed intranet, we click the API link in the help menu will got error message.
So, we can not enjoy the convenience of the api.

Suggest that adding environment variable in clowder docker compose file.
(for example..)

Also, you may add some detection mechanism like.. when we click the API and connect to web site failed, then
swith to local site.

Thanks!

Just want to clarify this issue title a little bit.

It is not related to the closed intranet. We need to specify the URL of the documentation in the config and env of docker.
