## Description

Update for logging changes

Remove `Context` from the `TxInfo` type and instead require the caller to pass a `Context` to `CheckTx` which is idiomatic.

closes: #6497

Addresses a beginning component of #6255

I believe that this, in my testing seems to help the e2e state-sync
tests complete more reliably, by fixing some potential, range-related
slice building, as well as the way the test app hashes snapshots.

Additionally, and I'm not sure if we want to do this, but I added this
hook to the reactor that re-sends the request for snapshots during the
retry. This helps in tests prevent systems from getting stuck, but I
think in reality, it might create more traffic, and operators would
just restart a state-syncing node to get a similar effect.

## Description

- return errors on `loadFilePv`

closes #6182

also

- replace `MaxReconnectAttempts`, `ReadWait`, `WriteWait` and `PingPeriod` options with `WSOptions` in `WSClient` (rpc/jsonrpc/client/ws_client.go).
- set default write wait to 10s for `WSClient`(rpc/jsonrpc/client/ws_client.go)
- unexpose `WSEvents`(rpc/client/http.go)

Closes #6162

## Description 

- Reduce duplication in messages and metrics. 
- merge WAL interfaces. Meant to push the developer to make changes in both places.

This cleans up the `Router` code and adds a bunch of tests. These sorts of systems are a real pain to test, since they have a bunch of asynchronous goroutines living their own lives, so the test coverage is decent but not fantastic. Luckily we've been able to move all of the complex peer management and transport logic outside of the router, as synchronous components that are much easier to test, so the core router logic is fairly small and simple.

This also provides some initial test tooling in `p2p/p2ptest` that automatically sets up in-memory networks and channels for use in integration tests. It also includes channel-oriented test asserters in `p2p/p2ptest/require.go`, but these have primarily been written for router testing and should probably be adapted or extended for reactor testing.

E2E tests often fail because validators miss signing or proposing blocks. Often this is because e.g. there's a lot of disruption in the network or it takes a long time to start up all the nodes.

This changes the test criteria to only check for 3 signed/proposed blocks, rather than a fraction of the expected blocks. This should be enough to catch most issues, apart from performance problems causing nodes to miss signing/proposing, but we may want separate tests for those sorts of things.

This revises the new P2P `Transport` interface and does some preliminary code cleanups and simplifications.

The major change here is to add `Connection.Handshake()` for performing node handshakes (once the stream transport API is implemented, this can be done entirely independent of the transport).  This moves most of the handshaking logic into the `Router`, such as prevention of head-of-line blocking, validation of peer's `NodeInfo`, controlling timeouts, and so on. This significantly simplifies transports, completely removes the need for internal goroutines, and shares common logic across all transports. This also allows varying the handshake `NodeInfo` across peers, e.g. to vary `ListenAddr`. Similarly, connection filtering is also moved into the switch/router so that it can be shared between transports.
