When receiving a message with save a contact in the database in order to
avoid re-calculating image/profile.
This contact is then passed to the client, which can negatively impact
performance.
This commit changes the behavior so that only those contacts that have
some custom fields (have been explicitly added by the user, have been
blocked by the user, have sent a contact request or have a verified ens
name) are passed to the client.
Currently ENS are verified explicitly by status-react, this is not ideal
as if that fails it will have to be explicilty retried in status-react.
This commits changes that behavior so that ENS are verified in a loop
and updated if new messages are received.
This commit pegs the clock value to maximum + 120 seconds from the whisper
timestamp.
In this way the we avoid the scenario where a client makes the timestamp
increase arbitrarely.
* Use a single Message type `v1/message.go` and `message.go` are the same now, and they embed `protobuf.ChatMessage`
* Use `SendChatMessage` for sending chat messages, this is basically the old `Send` but a bit more flexible so we can send different message types (stickers,commands), and not just text.
* Remove dedup from services/shhext. Because now we process in status-protocol, dedup makes less sense, as those messages are going to be processed anyway, so removing for now, we can re-evaluate if bringing it to status-go or not.
* Change the various retrieveX method to a single one:
`RetrieveAll` will be processing those messages that it can process (Currently only `Message`), and return the rest in `RawMessages` (still transit). The format for the response is:
`Chats`: -> The chats updated by receiving the message
`Messages`: -> The messages retrieved (already matched to a chat)
`Contacts`: -> The contacts updated by the messages
`RawMessages` -> Anything else that can't be parsed, eventually as we move everything to status-protocol-go this will go away.
