What is done in this PR:

    JSONRPCClient: validate that Response.ID matches Request.ID I wanted
    to do the same for the WSClient, but since we're sending events as
    responses, not notifications, checking IDs would require storing
    them in memory indefinitely (and we won't be able to remove them
    upon client unsubscribing because ID is different then).

    Request.ID is now optional. Notification is a Request without an ID.
    Previously "" or 0 were considered as notifications

    Remove #event suffix from ID from an event response (partially fixes
    #2949) ID must be either string, int or null AND must be equal to
    request's ID. Now, because we've implemented events as responses, WS
    clients are tripping when they see Response.ID("0#event") !=
    Request.ID("0"). Implementing events as requests would require a lot
    of time (~ 2 days to completely rewrite WS client and server)

    generate unique ID for each request

    switch to integer IDs instead of "json-client-XYZ"
    id=0 method=/subscribe
    id=0 result=...
    id=1 method=/abci_query
    id=1 result=...

> send events (resulting from /subscribe) as requests+notifications (not
responses)

this will require a lot of work. probably not worth it

* rpc: generate an unique ID for each request
in conformance with JSON-RPC spec

* WSClient: check for unsolicited responses

* fix golangci warnings

* save commit

* fix errors

also, use t.Rate in tm-bench indexer when calculating ID
