allow configuration of oidc client timeout

[jmacvey]

Describe the problem you'd like to have solved

We have an internal oidc issuer whose response time is less than performant. To accommodate them, I'd like to be able to configure the http timeout. If I leverage the openid-client package directly without using the sdk, I can do the following:

const { custom } = require('openid-client')

custom.setHttpOptionsDefaults({
  timeout: 10000, // set custom timeout
})

This doesn't work with the SDK, however, because the timeout is always overridden to 5000ms in client.js.

Describe the ideal solution

Depends. If you want to control the interface, you could expose a timeout option on the ConfigParams object. Otherwise the quick solution would be to just to check if the timeout if null / undefined just before you set it in client.js, and let consumers override default http options using the underlying open-id client package as shown above.

Alternatives and current work-arounds

Haven't considered alternatives. If the above sounds like a good idea let me know and I'll submit a PR.

Thanks!

Yep - good idea, thanks @jmacvey

If you raise a PR can you call the config param httpTimeout and set it in ms
