fix: make SlashPacketData backward compatible when sending data over the wire #1093

Description

Closes: #1092

Fixes communication between v1/2 provider and v3 consumer chains.

The incompatibility arises from the fact that ICS v3 uses cosmos-sdk slashing proto definitions, whereas ICS <= v2 uses custom proto definitions.

The underlying ENUM type is the same in both types but unfortunately ICS is configured to send packet data as JSON byte arrays.

When the internal proto types are marshalled, they yield different JSON byte arrays that are sent over the wire.

ICS v1/v2 (cosmos-sdk v45, ibc-go v4):

{
    "type": "CONSUMER_PACKET_TYPE_SLASH",
    "slashPacketData": {
        "validator": {
            "address": "",
            "power": "1"
        },
        "valset_update_id": "1",
        "infraction": "INFRACTION_TYPE_DOWNTIME"  // this is a different string, but the proto enum INT is 1
    }
}

ICS v3-rc (cosmos-sdk v47, ibc-go v7):

{
    "type": "CONSUMER_PACKET_TYPE_SLASH",
    "slashPacketData": {
        "validator": {
            "address": "",
            "power": "1"
        },
        "valset_update_id": "1",
        "infraction": "INFRACTION_DOWNTIME" // this is a different string, but the proto enum INT is 1
    }
}

The (hopefully temporary) fix

The consumer chain will always send packets in a format that is backward compatible with versions v1&2. The consumer will store the data using new proto types from cosmos-sdk, so that no state breaks arise.

The provider in ICSv3 was updated to be able to support V1/2 and V3 SlashPacketData. The data will always be stored using the new data types.

Thanks for the work! I have a few comments to reduce technical debt, also we should make some integration tests for this before giving to Stride

It doesn't seem it will land in SDK before 0.50 though.

Opened an issue #1105 in case this has to become permanent.

If we have to keep it in, we can fix it properly, draft PR with permanent solution will be opened soon.

## Description

Currently the `AppModule` assumes a single scoped keeper. This doesn't allow the mock module to be used as a base application for different middleware stack (ica stack, fee stack, etc)

I broke the API because I think it is cleaner. If we want this to be non API breaking, I can try to readjust

* fix: correctly claim capability for mock module, handle genesis exports (#921)

## Description

This contains two fixes:
- the capability being claimed by the scoped keeper was incorrect (mock.ModuleName -> port ID)
- the mock module wasn't accounting for non empty genesis state in capabilities (after genesis export, capability will create the bound ports so rebinding doesn't need to happen)

* 02-client: merge misbehavior & header interfaces (#1107)

* refactor: allow the mock module to be used multiple times as base ibc application in middleware stack (#892)

## Description

Currently the `AppModule` assumes a single scoped keeper. This doesn't allow the mock module to be used as a base application for different middleware stack (ica stack, fee stack, etc)

I broke the API because I think it is cleaner. If we want this to be non API breaking, I can try to readjust

* fix: correctly claim capability for mock module, handle genesis exports (#921)

## Description

This contains two fixes:
- the capability being claimed by the scoped keeper was incorrect (mock.ModuleName -> port ID)
- the mock module wasn't accounting for non empty genesis state in capabilities (after genesis export, capability will create the bound ports so rebinding doesn't need to happen)

## Description

Currently the `AppModule` assumes a single scoped keeper. This doesn't allow the mock module to be used as a base application for different middleware stack (ica stack, fee stack, etc)

I broke the API because I think it is cleaner. If we want this to be non API breaking, I can try to readjust

* fix: correctly claim capability for mock module, handle genesis exports (#921)

## Description

This contains two fixes:
- the capability being claimed by the scoped keeper was incorrect (mock.ModuleName -> port ID)
- the mock module wasn't accounting for non empty genesis state in capabilities (after genesis export, capability will create the bound ports so rebinding doesn't need to happen)
