commit 8e3e8860fdfe6c857adf8006879adedb4e673244
Author: Tien Mai <tienmai@chromium.org>

Add password change flow for when user changes their Gaia password.

The UI flow for GCPW is now as follows:
- "Reauth" is enabled for all gaia associated users
- After the user has signed in through gaia, if their gaia password does
not match their windows password, they will be asked to provide their
current windows password so that it can be changed to match the gaia
password.
- The same flow is applied to both logon types (reauth and add person)
- Removed a lot of code that is unnecssary for reauth calculation
- Refactored the flow of code so that WaitForLoginUI only returns the
authentication information gather through the GLS. This information
is passed onto OnUserAuthenticated to further process Windows specific
information used for logon.
