Add ability to include HTTP authentication on data requests

[ashleysommer]

I am referring in particular to WPS requests, but the same question could be asked of WMS/WCS layer requests too.

I have a WPS server that is adding the requirement of token authentication. All (getcapabilities, describeprocess, execute) requests must include one of:

• Authorization with "Bearer <myapikey>"
• Authorization header with "APIKey-1 <terntoken>"
• HTTP Basic auth with credentials "apikey:<terntoken>"

Any of these options will work, but TerriaJS doesn't have the ability at add any form of credentialisation that I am aware of.

Looks like the override of fetch and the ES6 fetch API can be made to send API requests with authentication headers to other origins.

Hi @ashleysommer

TerriaJS currently doesn't have a way to add credentials to requests - TerriaJS-server does have the proxyAuth function which allows credentials to be added to requests without revealing them to users

For example
