129291e848 Use interface name instead of cluster name
The cluster name option is not required anymore and
removed, the interface name is used to name the cluster
directly. For backward compatibility, the old path for storing
cluster state is tried as a fallback when loading.

f1de2def7f Add Banner and StatePath settings
Banner is used to carry a custom etc/hosts banner while StatePath holds
the path to cluster state storage.

61988692a1 Parse arguments in the tests entrypoint
Add an argument parsing routine to the tests entrypoint, and use it
to parse the interface name, passed to
wireguard-go.

e9b9239eae Reinstante cluster.LocalNode
This makes for more straightforward calls. Also, generate
the localNode directly in wg.New.

5b6923c272 Unexporter AssignOverlayAddress
Instead, the overlay address is assigned upon creation.
Also, the wireguard state is responsible for populating
the local node object.

faf1c35d96 Implement the delegate interface on Node
Implementing on Node makes a bit more sense than implementing on Cluster
even if the difference in code is insignificant.

Instead of using a trivial function, simply generate the
local node from main.go, manually assign fields from the
nodeMeta struct.

0162f9da2c Add unit tests for state functions

46da51b7aa Implement node function as type functions
This means nodeMeta can be private again, and also makes it
easier to pass a Node object to the cluster for local meta,
instead of a generic byte[] function.

For later updating, that node is passed using Update() instead
of New().

Splitting into modules will help keep concerns separate,
at the cost of a slightly more verbose code.

0e799d6074 Parse metadata outside of cluster.go
Move the calls for metadata decoding from the cluster
membership management loop to the main loop. This task
was not directly related to the cluster, and was adding
complexity, including the need for multierr structures.

366f906d5d Do not pass the config object to newCluster
Decouple the config structure from the cluster management and

97525f4b10 Stop using wireguard in cluster.go
The wireguard is mostly used to compute metadata.
Metadata is now computed by main.go and encoded in
node.go, the cluster only receives a function generating
the binary metadata.

0d93439d0d Move node related stuff to node.go
The cornerstone for exchanging data is the node
structure and associated metadata. Moving it to a
separate file (maybe later a separate module) will help
decoupling.
