When a user signs out of SCORE, we also sign out of CK Board.

Test with the ck-board branch from this PR

1. Find your local IP by running this in the Terminal.

ipconfig getifaddr en0

2. Modify your src/main/resources/application-dockerdev.properties file by adding this new property below. Replace 192.168.86.29 with your local IP.

ck_board_local_backend_url=http://192.168.86.29:8001

3. Start up SCORE, ck-board frontend, and ck-board backend.

4. Sign in to SCORE.

5. Open CK Board in a new tab. You should be automatically logged in.

6. Sign out of SCORE.

7. Go to the CK Board tab and refresh it. You should be logged out of CK Board and it should redirect you to the sign in page.

Closes #7

I was able to successfully log out in both directions (SCORE logs out the CK Board and CK Board logs out SCORE). In both cases it was not immediately apparent that the session had expired for the partner app but after clicking on links or refreshing the page then I was redirected to the login page. Perhaps (in the future) each app can handle the expired/ended session by redirecting the user more immediately to the login page?

Once again, looks great! I think we're good to merge.
