the docs for wdc on server could do with some work

[henryw374]

The docs in this project https://github.com/tableau/webdataconnector/blob/master/docs/wdc_use_in_server.md don't contain any detail about whitelisting, whilst the docs they point to (https://help.tableau.com/current/server/en-us/datasource_wdc.htm) contain an example that is a real wdc, but for which the config would be wrong (see dtreskunov/wta-wdc#1).

It's a shame that the community connectors don't each include a minimal whitelist config as far as I can see.

I also tried using a json entity file, as described in https://help.tableau.com/current/server/en-us/entity_wdc.htm, but the secondary whitelist didn't work - because (https://stephdietzel.github.io/*) should be (https://stephdietzel.github.io/(.*)) - on windows at least. And when refreshing we couldn't see any useful log output in the tableau server, the refresh just times out.

The clearest documentation I found for wdc whitelist was contributed by a user in this ticket: #417 (comment)

Agreed, I'll see if we can get them updated soon!
