Why make the change?
This implements waku/1 which is a breaking change as waku/0 diverged
from the specs.
What has changed?
- Added v1 namespace
- Changed the testing code to test from the outside rather than stubbing
p2p specific messages, so that any version specific code is under `vx`
namespaces
- Split waku vs waku/x test code
- Added a test suite that can be used for different versions
Things still to do
I kept the tests we have for the versioned aspect of waku, probably we
want to add some or change other to provide the optimal test coverage.
This commit creates a waku/1 namespace and adds the code to it.
No changes in the protocol have been made (i.e waku/1 is the same as
waku/1 in this commit).
