Jess/381 pod linking

Description

This allows a user logged in to their webid to view their webid file, eg jessicamoore/profile/card$.ttl and link another pod on another Solid server by temporarily adding the oidcRegistrationToken of server 2, and adding server 2 as a oidcIssuer.

I followed these steps to test this PR.

1. Register a CSS account, and create a POD (in section Pods, click the Create pod link, provide the POD name, and choose to use an external WebID, say WebID1).

2. Link the WebID used in step 1 (i.e., WebID1) to the CSS account (in section Registered Web IDs of the above screenshot, click Link WebID), after clicking Link WebID to account`, a page with registration token is shown.

3. Use a solidui based app, login with a CSS account linked with WebID1 (not the newly registered account), go to the profile page, click Link another Pod, and provide the POD server URL and the token from step 2, click Add Token. Then follow the on-screen instructions in the app to finishing the linking.

4. After successfully linking WebID1 with a newly created POD (and the corresponding CSS account), one can then login a solidui based app using the new CSS account and WebID1.

The functionality worked as expected in my test, as noted in this comment, thanks Jess.

One observation: The current implementation does not seem to check if a server has already been linked, so it's possible to link the same server multiple times (as shown in the screenshot below).

Thanks Dawei, the last commit should have prevented duplicate oidcIssuers, but looks like it didn't catch your use pattern. I'll check and fix it.
