Summary of Bug

all (g)RPC queries that return multiple items are missing proper pagination

Version

Steps to Reproduce

• Send > 100 packets:
  $ hermes tx raw ft-transfer ibc-0 ibc-1 transfer channel-0 9999 15 -n 500
• Query packet commitments will return less than 500
  hermes query packet unreceived-packets ibc-1 ibc-0 transfer channel-0

Found this while I was debugging why hermes start doesn't clear all packets on start.

Acceptance Criteria

All gRPC queries that return collections should be looked at. Here is a list (needs to be updated after we release v0.2.0:

• query_clients
• query_client_connections - proto QueryClientConnectionsRequest doesn't have pagination
• query_connections
• query_connection_channels
• query_channels
• query_packet_commitments
• query_unreceived_packets- proto QueryUnreceivedPacketsRequest doesn't have pagination - not needed as we ask for specific sequences
• query_packet_acknowledgements
• query_unreceived_acknowledgements - proto QueryUnreceivedAcksRequest doesn't have pagination - not needed as we ask for specific sequences
• query_consensus_states

This is using tendermint rpc and should also be fixed:

• query_txs
