replace ephemeral deletion logic (#2008)
* 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

Replace database locks with transactions (#1701)
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.

* 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.

Kristoffer Dalby 66ff1fcd40 Replace the timestamp based state system
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.

Kristoffer Dalby 725bbd7408 Remove variables and leftovers of pregenerated ACL content
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.
