I think also fixes #2868

[adizere]

What do you think about untangling this PR to separate the changes related to issue 2868 apart from issue 2867?

Context:

• I think we can merge the changes related to Hermes tx CLIs that use packet_data_query_height should also clear begin/end block events #2868 ASAP. They look solid.
• As for Hermes sometimes fails to retrieve the begin/end block events #2867 this is more complex.
  • Jasmina proposed a Tendermint-level fix in this PR state/kvindexer: associate event attributes with events tendermint/tendermint#9759
  • With these changes in place we can query from Hermes using the new match.events flag.
  • This requires tendermint-rs changes, so it will be a bit more work to push that through, but it's a long term fix.
  • In order to unblock the Tendermint team, it would be good if we give them feedback on their PR.

Summary:

• We can fix Hermes tx CLIs that use packet_data_query_height should also clear begin/end block events #2868 by trimming down the present PR (or a new PR with the right changes)
• We can open a new PR to test E2E if the changes in Tendermint (state/kvindexer: associate event attributes with events tendermint/tendermint#9759) are sufficient to fix Hermes sometimes fails to retrieve the begin/end block events #2867.
  • If yes, we give the feedback to TM team and go with that
  • If no, we retain the solution in this PR

I'll take a look at the tendermint PR and run a custom hermes version that uses that. But it seems that we still need to temp fix hermes with the PR here until all chains move to the new tendermint version.

lgtm, thanks @romac!
