Previously, Headscale would only use the `email` OIDC
claim to set the Headscale user. In certain cases
(self-hosted SSO), it may be useful to instead use the
`preferred_username` to set the Headscale username.
This also closes #938.
This adds a config setting to use this claim instead.
The OIDC docs have been updated to include this entry as well.
In addition, this adds an Authelia OIDC example to the docs.
Added OIDC claim integration tests.
Updated the MockOIDC wrapper to take an environment variable that
lets you set the username/email claims to return.
Added two integration tests, TestOIDCEmailGrant and
TestOIDCUsernameGrant, which check the username by checking the FQDN of
clients.
Updated the HTML template shown after OIDC login to show whatever
username is used, based on the Headscale settings.
This commit simplifies the goreleaser configuration and then adds nfpm
support which allows us to build .deb and .rpm for each of the ARCH we
support.
The deb and rpm packages adds systemd services and users, creates
directories etc and should in general give the user a working
environment. We should be able to remove a lot of the complicated,
PEBCAK inducing documentation after this.

This commit adds a default OpenID Connect expiry to 180d to align with
Tailscale SaaS (previously infinite or based on token expiry).
In addition, it adds an option use the expiry time from the Token sent
by the OpenID provider. This will typically cause really short expiry
and you should only turn on this option if you know what you are
desiring.
This fixes #1176.

Currently the most "secret" way to specify the oidc client secret is via
an environment variable `OIDC_CLIENT_SECRET`, which is problematic[1].
Lets allow reading oidc client secret from a file. For extra convenience
the path to the secret will resolve the environment variables.

Adds knobs to configure three aspects of the OpenID Connect flow:
* Custom scopes to override the default "openid profile email".
* Custom parameters to be added to the Authorize Endpoint request.
* Domain allowlisting for authenticated principals.
* User allowlisting for authenticated principals.
Websockets, in which DERP is based, requires a TLS certificate. At the same time,
if we use a certificate it must be valid... otherwise Tailscale wont connect (does not
have an Insecure option). So there is no option to expose insecure here
