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.

Previously we did not update the packet filter
when nodes changed, which would cause new nodes
to be missing from packet filters of old nodes.

This commits extends the mapper with functions for creating "delta"
MapResponses for different purposes (peer changed, peer removed, derp).
This wires up the new state management with a new StateUpdate struct
letting the poll worker know what kind of update to send to the
connected nodes.

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.

There was a lot of tests that actually threw a lot of errors and that did
not pass all the way because we didnt check everything. This commit should
fix all of these cases.

This commit makes a wrapper function round the normalisation requiring
"stripEmailDomain" which has to be passed in almost all functions of
headscale by loading it from Viper instead.

This commit allows SSH rules to be assigned to each relevant not and
by doing that allow SSH to be rejected, completing the initial SSH
support.
