There is a chance that offline storage could fall out of sync with the
refresh token tables. One example is if dex crashes/is stopped in the
middle of handling a login request. If the old refresh token associated
with the offline session is deleted, and then the process stops, the
offline session will still refer to the old token.
Unfortunately, if this case occurs, there is no way to recover from it,
since further logins will be halted due to dex being unable to clean up
the old tokens till referenced in the offline session: the database is
essentially corrupted.
There doesn't seem to be a good reason to fail the auth request if the
old refresh token is gone. This changes the logic in `handleAuthCode` to
not fail the entire transaction if the old refresh token could not be
deleted because it was not present. This has the effect of installing
the new refresh token, and unpdating the offline storage, thereby fixing
the issue, however it occured.
Now, we'll return a standard error, and have the caller act upon this
being an instance of authErr.
Also changes the storage.AuthRequest return to a pointer, and returns
nil in error cases.

Before, you could not POST your credentials to a password-connector's
endpoint without GETing that endpoint first. While this makes sense for
browser clients; automated interactions with Dex don't need to look at
the password form to fill it in.
A symptom of that missing GET was that the POST succeeded (!) with
login successful: connector "", username="admin", email="admin@example.com", groups=[]
Note the connector "". A subsequent call to finalizeLogin would then
fail with
connector with ID "" not found: failed to get connector object from storage: not found
Now, the connector ID of an auth request will be updated for both GETs
and POSTs.

This way, the user who has selected, say, "Log in with Email" can make up
their mind, and select a different connector instead.
However, if there's only one connector set up, none of this makes sense -- and
the link will thus not be displayed.

This allows users of the LDAP connector to give users of Dex' login
prompt an idea of what they should enter for a username.
Before, irregardless of how the LDAP connector was set up, the prompt
was
Username
[_________________]
Password
[_________________]
Now, this is configurable, and can be used to say "MyCorp SSO Login" if
that's what it is.
If it's not configured, it will default to "Username".
For the passwordDB connector (local users), it is set to "Email
Address", since this is what it uses.
