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.

Align behaviour of dns_config.restricted_nameservers to tailscale.
Tailscale allows split DNS configuration without requiring global nameservers.
In addition, as per [the docs](https://tailscale.com/kb/1054/dns/#using-dns-settings-in-the-admin-console):
> These nameservers also configure search domains for your devices
This commit aligns headscale to tailscale by:
* honouring dns_config.restricted_nameservers regardless of whether any global resolvers are configured
* adding a search domain for each restricted_nameserver
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.

Add a configuration flag (default true to preserve current behaviour) to
allow headscale to start without OIDC being able to initialise.

Extract LoadConfig from GetHeadscaleConfig, as they are conceptually
different operation, e.g.,
1) you can reload config through LoadConfig and do not get config
2) you can get config without reload config
