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 rearranges the poll handler to immediatly accept
updates and notify its peers and return, not travel down the
function for a bit. This reduces the DB calls and other
holdups that isnt necessary to send a "lite response", a
map response without peers, or accepting an endpoint update.

This field is no longer used, it was used in our old state
"algorithm" to determine if we should send an update.

This commit changes the internals of the mapper to
track all the changes to peers over its lifetime.
This means that it no longer depends on the database
and this should hopefully help with locks and timing issues.
When the mapper is created, it needs the current list of peers,
the world view, when the polling session was started. Then as
update changes are called, it tracks the changes and generates
responses based on its internal list.
As a side, the types.Machines and types.MachinesP, as well as
types.Machine being passed as a full struct and pointer has been
changed to always be pointers, everywhere.

Previously we did not update the packet filter
when nodes changed, which would cause new nodes
to be missing from packet filters of old nodes.

This commits extends the mapper with functions for creating "delta"
MapResponses for different purposes (peer changed, peer removed, derp).
This wires up the new state management with a new StateUpdate struct
letting the poll worker know what kind of update to send to the
connected nodes.

This commit replaces the timestamp based state system with a new
one that has update channels directly to the connected nodes. It
will send an update to all listening clients via the polling
mechanism.
It introduces a new package notifier, which has a concurrency safe
manager for all our channels to the connected nodes.

There was a lot of tests that actually threw a lot of errors and that did
not pass all the way because we didnt check everything. This commit should
fix all of these cases.
