* make stream shutdown if self-node has been removed
Currently we will read the node from database, and since it is
deleted, the id might be set to nil. Keep the node around and
just shutdown, so it is cleanly removed from notifier.

* Add support for service reload and sync service file
* Copy the systemd.service file to the manual linux docs and adjust the
path to the headscale binary to match with the previous documentation
blocks. Unfortunately, there seems to be no easy way to include a
file in mkdocs.
* Remove a redundant "deprecation" block. The beginning of the
documentation already states that.
* Add `ExecReload` to the systemd.service file.
Fixes: #2016
* Its called systemd
* Fix link to systemd homepage
* Fix KeyExpiration when a zero time value has a timezone
When a zero time value is loaded from JSON or a DB in a way that
assigns it the local timezone, it does not roudtrip in JSON as a
value for which IsZero returns true. This causes KeyExpiry to be
treated as a far past value instead of a nilish value.

* validate policy against nodes, error if not valid
this commit aims to improve the feedback of "runtime" policy
errors which would only manifest when the rules are compiled to
filter rules with nodes.
this change will in;
file-based mode load the nodes from the db and try to compile the rules on
start up and return an error if they would not work as intended.
database-based mode prevent a new ACL being written to the database if
it does not compile with the current set of node.

this commit changes and streamlines the dns_config into a new

configuration options that made it easy to confuse what headscale

* fix start -> strategy which was wrongly corrected by linter
* 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
time. This time is now only set when a node disconnects and
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.
Fixes#2006

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.

We currently do not have a way to clean up api keys. There may be cases
where users of headscale may generate a lot of api keys and these may
end up accumulating in the database. This commit adds the command to
delete an api key given a prefix.
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.
