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.

Switch from using "text/template" to "html/template", which provides
basic XSS preventions. We haven't identified any particular place
where unsanitized user data is rendered to the frontend. This is
just a preventative step.
At the same time, make more templates take pure URL instead of
forming an URL themselves using an "authReqID" argument. This will
help us stop using the auth req ID in certain places, preventing
garbage collection from killing login flows that wait too long at
the login screen.
Also increase the login session window (time between initial
redirect and the user logging in) from 30 minutes to 24 hours,
and display a more helpful error message when the session expires.
How to test:
1. Spin up dex and example with examples/config-dev.yaml.
2. Login through both the password prompt and the direct redirect.
3. Edit examples/config-dev.yaml removing the "connectors" section.
4. Ensure you can still login with a password.
(email/password is "admin@example.com" and "password")
"state" means something specific to OAuth2 and SAML so we don't
want to confuse developers who are working on this.
Also don't use "session" which could easily be confused with HTTP
cookies.
