refactor(Social Login): Extract common code to abstract class

[hirokiterashima]

Changes

• Extract common code in GoogleOpenIdConnectFilter and MicrosoftOpenIdConnectFilter to AbstractOpenIdConnectFilter
  • Note: there are still some duplicate code in attemptAuthentication() method. The functions behaves slightly differently in Google and Microsoft, and requires a change in application behavior to safely refactor. You can ignore these for now. I'll handle them in a separate task.

Test Prep

• Test with login-with-microsoft client branch
• In application-docker-dev.properties, add ?prompt=select_account at the end of microsoft.userAuthorizationUri property. This will make you select the Microsoft account each time you login. It adds an additional click, but it prevents issues when you're signed in as another MS user but want to sign in as a different MS user for WISE.

Test (with Google account and Microsoft account)

Verify that these work as before:

• Sign in
• Register user
