grpc/grpc-go#2627
prometheous change:
due to UninstrumentedHandler, being deprecated in the future
empty branch = empty if or else statement
didn't delete them entirely but commented
couldn't find a reason to have them
could not replicate the issue #3406
but if want to keep it commented then we should comment out the if statement as well
## PR
This PR introduces a fundamental breaking change to the structure of ABCI response and tx tags and the way they're processed. Namely, the SDK can support more complex and aggregated events for distribution and slashing. In addition, block responses can include duplicate keys in events.
Implement new Event type. An event has a type and a list of KV pairs (ie. list-of-lists). Typical events may look like:
"rewards": [{"amount": "5000uatom", "validator": "...", "recipient": "..."}]
"sender": [{"address": "...", "balance": "100uatom"}]
The events are indexed by {even.type}.{even.attribute[i].key}/.... In this case a client would subscribe or query for rewards.recipient='...'
ABCI response types and related types now include Events []Event instead of Tags []cmn.KVPair.
PubSub logic now publishes/matches against map[string][]string instead of map[string]string to support duplicate keys in response events (from #1385). A match is successful if the value is found in the slice of strings.
closes: #1859closes: #2905

==================
```
lite client works (tested manually)
godoc comments
httpclient: do not close the out channel
use TimeoutBroadcastTxCommit
no timeout for unsubscribe
but 1s Local (5s HTTP) timeout for resubscribe
format code
change Subscribe#out cap to 1
and replace config vars with RPCConfig
TimeoutBroadcastTxCommit can't be greater than rpcserver.WriteTimeout
rpc: Context as first parameter to all functions
reformat code
fixes after my own review
fixes after Ethan's review
add test stubs
fix config.toml
* fixes after manual testing
- rpc: do not recommend to use BroadcastTxCommit because it's slow and wastes
Tendermint resources (pubsub)
- rpc: better error in Subscribe and BroadcastTxCommit
- HTTPClient: do not resubscribe if err = ErrAlreadySubscribed
* fixes after Ismail's review
* Update rpc/grpc/grpc_test.go
Co-Authored-By: melekes <anton.kalyaev@gmail.com>
* green pubsub tests :OK:
* get rid of clientToQueryMap
* Subscribe and SubscribeUnbuffered
* start adapting other pkgs to new pubsub
* nope
* rename MsgAndTags to Message
* remove TagMap
it does not bring any additional benefits
* bring back EventSubscriber
* fix test
* fix data race in TestStartNextHeightCorrectly
```
