Hermes `clear_on_start` toggle does not work

[adizere]

Crate

ibc-relayer and ibc-relayer-cli

Summary of Bug

It seems that configuring clear_on_start = false does not work. When this is set to false, Hermes should not try to clear packets at startup. But this is not the case. Instead, we're hardcoding that the clearing should always happen

https://github.com/informalsystems/ibc-rs/blob/aef0e6a92736239d50048e35c73c5eca8c9b7814/relayer/src/link/relay_path.rs#L125

The problem was reported by a relayer operator on Bandchain network. They are probably the only ones using clear_on_start = false (I'm not aware of other operators using false here, and we don't have tests covering this feature, hence this bug went unnoticed for quite some time).

Logs folded here, but not sure they are truly useful. The more important part is the "steps to reproduce" described below.

Version

v0.11.1

Steps to Reproduce

1. Setup a two chain network using gm. Suppose the two networks and ibc-0 and ibc-1.
2. Setup a channel-0 between the two networks.
3. Trigger and ft-transfer on channel-0 of ibc-0

   • ./target/debug/hermes --json tx raw ft-transfer ibc-1 ibc-0 transfer channel-0 100 -d samoleans -t 1800 -n 1

4. Configure clear_on_start to be false in the config.toml of Hermes.
   • Make sure your log level is set to log_level = 'debug'.
   • Also set clear_interval = 0 to completely disable periodic packet clearing.
5. Do hermes start.
   • Notice the log output and it should be visible that Hermes will clear the outstanding packets.
   • The main indicator of this is the clear{} span appearing in the log lines:

   • 2022-02-15T10:15:09.764808Z INFO ThreadId(01) Hermes has started
     2022-02-15T10:15:19.908308Z DEBUG ThreadId(22) packet_cmd{src_chain=ibc-0 src_port=transfer src_channel=channel-2 dst_chain=ibc-1}:clear{f=false}: packet seq. that still have commitments on ibc-0: 8 (first 10 shown here; total=1)

Under normal circumstances, when clear_on_start = false, Hermes should not immediately clear packets upon startup.

Acceptance Criteria

• the clear_on_start option should translate into the correct Hermes behavior: if set to false, then hermes start should proceed to relaying live packets immediately (instead of relaying old packets)

Temporary solution here

https://github.com/informalsystems/ibc-rs/compare/anca/tempfix_noclear?expand=1

The full solution should ensure that clear_on_start option propagates from config.toml down in the RelayPath logic.
