* make reauth test compat with tailscale head
tailscale/tailscale@1eaad7d broke our reauth test as it makes the client
retry with https/443 if it reconnects within 2 minutes.
This commit fixes this by running the test as a two part,
- with https, to confirm instant reconnect works
- with http, and a 3 min wait, to check that it work without.
The change is not a general consern as headscale in prod is ran
with https.

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

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 denormalises the Tags related to a Pre auth key
back onto the preauthkey table and struct as a string list.
There was not really any real normalisation here as we just added

GORM cermony but no actual advantage.
This work is the start to fixup tags which currently are not working

* replace ephemeral deletion logic
this commit replaces the way we remove ephemeral nodes,
currently they are deleted in a loop and we look at last seen

there was a bug (#2006) where nodes that had never disconnected
was deleted since they did not have a last seen.
The new logic will start an expiry timer when the node disconnects
and delete the node from the database when the timer is up.
If the node reconnects within the expiry, the timer is cancelled.

This PR removes the complicated session management introduced in https://github.com/juanfont/headscale/pull/1791 which kept track of the sessions in a map, in addition to the channel already kept track of in the notifier.
Instead of trying to close the mapsession, it will now be replaced by the new one and closed after so all new updates goes to the right place.
The map session serve function is also split into a streaming and a non-streaming version for better readability.
RemoveNode in the notifier will not remove a node if the channel is not matching the one that has been passed (e.g. it has been replaced with a new one).
A new tuning parameter has been added to added to set timeout before the notifier gives up to send an update to a node.
Add a keep alive resetter so we wait with sending keep alives if a node has just received an update.
In addition it adds a bunch of env debug flags that can be set:
- `HEADSCALE_DEBUG_HIGH_CARDINALITY_METRICS`: make certain metrics include per node.id, not recommended to use in prod.
- `HEADSCALE_DEBUG_PROFILING_ENABLED`: activate tracing
- `HEADSCALE_DEBUG_PROFILING_PATH`: where to store traces
- `HEADSCALE_DEBUG_DUMP_CONFIG`: calls `spew.Dump` on the config object startup
- `HEADSCALE_DEBUG_DEADLOCK`: enable go-deadlock to dump goroutines if it looks like a deadlock has occured, enabled in integration tests.

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.

When Postgres is used as the backing database for headscale,
it does not set a limit on maximum open and idle connections
which leads to hundreds of open connections to the Postgres
server.
This commit introduces the configuration variables to set those
values and also sets default while opening a new postgres connection.
This commits removes the locks used to guard data integrity for the
database and replaces them with Transactions, turns out that SQL had
a way to deal with this all along.
This reduces the complexity we had with multiple locks that might stack
or recurse (database, nofitifer, mapper). All notifications and state
updates are now triggered _after_ a database change.

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.
