* consensus: calculate prevote message delay metric (#7551)

## What does this pull request do?
This pull requests adds two metrics intended for use in calculating an experimental value for `MessageDelay`.

The metrics are as follows:
```
# HELP tendermint_consensus_complete_prevote_message_delay Difference in seconds between the proposal timestamp and the timestamp of the prevote that achieved 100% of the voting power in the prevote step.
# TYPE tendermint_consensus_complete_prevote_message_delay gauge
tendermint_consensus_complete_prevote_message_delay{chain_id="test-chain-aZbwF1"} 0.013025505

# HELP tendermint_consensus_quorum_prevote_message_delay Difference in seconds between the proposal timestamp and the timestamp of the prevote that achieved a quorum in the prevote step.
# TYPE tendermint_consensus_quorum_prevote_message_delay gauge
tendermint_consensus_quorum_prevote_message_delay{chain_id="test-chain-aZbwF1"} 0.013025505
```

## Why this change?

 For more information on what these metrics are calculating, see #7202. The aim is to merge to backport these metrics to v0.34 and run nodes on a few popular chains with these metrics to determine the experimental values for `MessageDelay` on these popular chains and use these to select our default `SynchronyParams.MessageDelay` value.

## Why Gauges for the metrics?
Gauges allow us to overwrite the metric on each successive observation. We can then capture these metrics over time to track the highest and lowest observed value.

If a subscriber arrives while the pubsub service is shutting down, the existing
code will return a nil subscription without error. With unlucky timing, this
may lead to a nil indirection panic in the RPC service.

To avoid that problem, make sure that when a subscription fails for this
reason, we report a non-nil error so that the client will detect it and give up
gracefully.

A workaround for #6729. Add parameters to control buffer sizes for
event subscription RPC clients. On some networks, buffering causes
clients to be dropped and/or events to be lost.

For additional context, see the discussion on #7188.

- Add experimental_subscription_buffer_size config parameter
- Add experimental_websocket_write_buffer_size config parameter
- Add experimental_close_on_slow_client config parameter

(cherry picked from commit befd669794)

* e2e: abci protocol should be consistent across networks (#7078)

It seems weird in retrospect that we allow networks to contain
applications that use different ABCI protocols.

(cherry picked from commit f2a8f5e054)

I accidentally omitted this from the backport in #6906.
Fixes #7043.

https://github.com/tendermint/tendermint/blob/v0.34.13/CHANGELOG.md#v0.34.12

This change backports the PostgreSQL indexing sink, addressing part of #6828.

Development on the main branch has diverged substantially since the v0.34.x
release. It includes package moves, breaking API and protobuf schema changes,
and new APIs, all of which together have a large footprint on the mapping
between the implementation at tip and the v0.34 release branch.

To avoid the need to retrofit all of those improvements, this change works by
injecting the new indexing sink into the existing (v0.34) indexing interfaces
by delegation. This means the backport does _not_ pull in all the newer APIs
for event handling, and thus has minimal impact on existing code written
against the v0.34 package structure.

This change includes the test for the `psql` implementation, and thus updates
some Go module dependencies. Because it does not interact with any other types,
however, I did not add any unit tests to other packages in this change.

Related changes:
 * Update module dependencies for psql backport.
 * Update test data to be type-compatible with the old protobuf types.
 * Add config settings for the PostgreSQL indexer.
 * Clean up some linter settings.
 * Hook up the psql indexer in the node main.
