Chrome Version       : 67.0.3396.99

Background:
We want to use browser for some automation in headless mode. Our use case requires user authentication.
Our tool would bring up browser with new/empty profile and ask user to sign in. Then it would retrieve cookies through chrome-remote-interface and save it to json file. It would then run browser in headless mode with new/empty profile and inject those cookies through chrome-remote-interface.

Issue:
This works for all accounts we tried except corp @google.com accounts.

I think this is because of channel-id feature, which is similar and would be (soon?) replaced with token-binding feature.
Headless chrome doesn't save/restore channel ids to/from database. And there's no api to get/set them in a similar way as cookies using chrome-remote-interface.

I think one of these options could solve our issue:
1. (preferred) add chrome-remote-interface api to get/set channel ids/token-binding ids
2. make headless chrome restore channel ids from database, so that we could reuse 'profile/Default/Origin Bound Certs' database file from regular chrome profile.
3. export chrome cmdline flag to disable channel id feature. Not sure if it will work. If this feature is disabled will it stop checking channel ids for auth or will auth stop working at all? But I guess this one would be the easiest to implement.

Easiest way to reproduce:
1. google-chrome --user-data-dir=profile https://myaccount.google.com
2. sign-in with @google.com, close chrome.
3. mkdir -p profile2/Default/ && cp profile/Default/Cookies profile2/Default && google-chrome --user-data-dir=profile2 https://myaccount.google.com
4. Observe that user is signed out. Close chrome.
5. cp 'profile/Default/Origin Bound Certs' profile2/Default && google-chrome --user-data-dir=profile2 https://myaccount.google.com
6. Observe that user is signed in. Close chrome.
7. google-chrome --headless --remote-debuggin-port=9222 --user-data-dir=profile2 https://myaccount.google.com
8. Connect to localhost:9222 and observe that user is logged out.
