Andrea Maria Piana e836ffb47f Soft blacklist peer ids
Why make this change?

This change is useful so we can blacklist peer ids, without actually
disconnecting them, so that it's harder for them to tell that they are
being blacklisted. Envelopes will just be dropped.

What has changed?

In waku we pass a config with a list of hex-encoded peer ids, and we
check that against newly received envelopes.
If so we just drop the envelope and return

Andrea Maria Piana aa7f591587 Move networking code for waku under `v0` namespace
Why make the change?

As discussed previously, the way we will move across versions is to maintain completely separate
codebases and eventually remove those that are not supported anymore.

This has the drawback of some code duplication, but the advantage is that is more
explicit what each version requires, and changes in one version will not
impact the other, so we won't pile up backward compatible code.
This is the same strategy used by `whisper` in go ethereum and is influenced by
https://www.youtube.com/watch?v=oyLBGkS5ICk .

All the code that is used for the networking protocol is now under `v0/`.
Some of the common parts might still be refactored out.
The main namespace `waku` deals with `host`->`waku` interactions (through RPC),
while `v0` deals with `waku`->`remote-waku` interactions.

In order to support `v1`, the namespace `v0` will be copied over, and changed to
support `v1`. Once `v0` will be not used anymore, the whole namespace will be removed.

This PR does not actually implement `v1`, I'd rather get things looked over to
make sure the structure is what we would like before implementing the changes.

What has changed?

- Moved all code for the common parts under `waku/common/` namespace
- Moved code used for bloomfilters in `waku/common/bloomfilter.go`
- Removed all version specific code from `waku/common/const` (`ProtocolVersion`, status-codes etc)
- Added interfaces for `WakuHost` and `Peer` under `waku/common/protocol.go`

Things still to do

Some tests in `waku/` are still testing by stubbing components of a particular version (`v0`).
I started moving those tests to instead of stubbing using the actual component, which increases
the testing surface. Some other tests that can't be easily ported should be likely moved under
`v0` instead. Ideally no version specif code should be exported from a version namespace (for
example the various codes, as those might change across versions). But this will be a work-in-progress.

Some code that will be common in `v0`/`v1` could still be extract to avoid duplication, and duplicated only
when implementations diverge across versions.

Add statusUpdate code ()
* Add status-option code

This commits changes the behavior of waku introducing a new status-code,
`2`, that replaces the current single options codes.
