mod_http_oauth2: Allow 'login_hint' as a substitute for OIDC 'select_account' prompt
If the OIDC 'prompt' parameter does not contain the 'select_account'
then it wants us to skip account selection, which means we have to
figure which account to authenticate somehow. One way could be have
this stored in a cookie from a previous successful login. Another way
would be to have the account passed as a hint, which is what we add
here.
