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.

Fixes the issue reported in #1712. In Tailscale SaaS, ephemeral keys can be single-user or reusable. Until now, our ephemerals were only reusable. This PR makes us adhere to the .com behaviour.
A lot of things are breaking in 0.23 so instead of having this
be a long process, just rip of the plaster.
Updates #1758

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.

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.

* 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 rearranges the poll handler to immediatly accept
updates and notify its peers and return, not travel down the
function for a bit. This reduces the DB calls and other
holdups that isnt necessary to send a "lite response", a
map response without peers, or accepting an endpoint update.

This field is no longer used, it was used in our old state
"algorithm" to determine if we should send an update.

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.
