* 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
key, dns. It removes a combination of outdates and incompatible
configuration options that made it easy to confuse what headscale
could and could not do, or what to expect from ones configuration.

* 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 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.
