currently, the policy approach node to user matching
with a quite naive approach looking at the username
provided in the policy and matched it with the username
on the nodes. This worked ok as long as usernames were
unique and did not change.
As usernames are no longer guarenteed to be unique in
an OIDC environment we cant rely on this.
This changes the mechanism that matches the user string
(now user token) with nodes:
- first find all potential users by looking up:
- database ID
- provider ID (OIDC)
- username/email
If more than one user is matching, then the query is
rejected, and zero matching nodes are returned.
When a single user is found, the node is matched against
the User database ID, which are also present on the actual
node.
This means that from this commit, users can use the following
to identify users in the policy:
- provider identity (iss + sub)
- username
- email
- database id
There are more changes coming to this, so it is not recommended
to start using any of these new abilities, with the exception
of email, which will not change since it includes an @.

expand user, add claims to user
This commit expands the user table with additional fields that
can be retrieved from OIDC providers (and other places) and
uses this data in various tailscale response objects if it is
available.
This is the beginning of implementing
https://docs.google.com/document/d/1X85PMxIaVWDF6T_UPji3OeeUqVBcGj_uHRM5CI-AwlY/edit
trying to make OIDC more coherant and maintainable in addition
to giving the user a better experience and integration with a
provider.
remove usernames in magic dns, normalisation of emails
this commit removes the option to have usernames as part of MagicDNS
domains and headscale will now align with Tailscale, where there is a
root domain, and the machine name.
In addition, the various normalisation functions for dns names has been
made lighter not caring about username and special character that wont
occur.
Email are no longer normalised as part of the policy processing.
untagle oidc and regcache, use typed cache
This commits stops reusing the registration cache for oidc
purposes and switches the cache to be types and not use any
allowing the removal of a bunch of casting.
try to make reauth/register branches clearer in oidc
Currently there was a function that did a bunch of stuff,
finding the machine key, trying to find the node, reauthing
the node, returning some status, and it was called validate
which was very confusing.
This commit tries to split this into what to do if the node
exists, if it needs to register etc.

This commit restructures the map session in to a struct
holding the state of what is needed during its lifetime.
For streaming sessions, the event loop is structured a
bit differently not hammering the clients with updates
but rather batching them over a short, configurable time
which should significantly improve cpu usage, and potentially
flakyness.
The use of Patch updates has been dialed back a little as
it does not look like its a 100% ready for prime time. Nodes
are now updated with full changes, except for a few things
like online status.

* make Node object use actualy tailscale key types
This commit changes the Node struct to have both a field for strings
to store the keys in the database and a dedicated Key for each type
of key.
The keys are populated and stored with Gorm hooks to ensure the data
is stored in the db.

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.

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.

Prior to the code reorg, we would generate rules from the Policy and
store it on the global object. Now we generate it on the fly for each node
and this commit cleans up the old variables to make sure we have no
unexpected side effects.
