[IBC] Create the initial IBC module

[h5law]

Objective

As outlined here the first phase of the IBC integration requires the implementation of both ICS-23 and ICS-24 before work can start on the ICS-02 (Light Client).

This issue encompasses the implementation of ICS-23 and ICS-24 (in part) alongside partially ICS-25 and doing so integrating them into the new IBC module in Pocket V1.

IBC Implementation Roadmap can be found here

Goals

• Create a new IBC module in Pocket V1
• Implement ICS-23
• Implement ICS-24 (in part)
• Implement ICS-25 (in part)
• Mock and unit test the initial IBC module and its components
• Add documentation

Deliverable

• [ ] Create a new IBC module
  • [ ] Write mocking tests for the module as it currently stands
  • [ ] Add configs to configure particular aspects of the IBC module
• [ ] Implement ICS-23
  • [x] #841
  • [ ] https://github.com/cosmos/ics23/issues/152
• [ ] Implement ICS-24
  • [x] #840
  • [ ] Add path-specific functionality
  • [ ] Add all currently implementable (relating to ICS-23, ICS-24 and ICS-25 alone) functionality
• [ ] Implement ICS-25
  • [ ] Add an interface that can be expanded as other ICS components are implemented
• [ ] Add testing
  • [ ] Add unit tests to cover the implemented functionality
  • [ ] Add mocks and integration tests as is appropriate
• [ ] Add documentation
  • [ ] Add module documentation
  • [ ] Add IBC related information and design information into the pocket repo/notion

Non-goals / Non-deliverables

• Implement any ICS module besides those listed above
• Fully implement the ICS-24 and ICS-25 components regarding their functionality relating to other ICS components

General issue deliverables

• [ ] Update the appropriate CHANGELOG(s)
• [ ] Update any relevant local/global README(s)
• [ ] Update relevant source code tree explanations
• [ ] Add or update any relevant or supporting mermaid diagrams

Testing Methodology

• [ ] Task specific tests or benchmarks: make ...
• [ ] New tests or benchmarks: make ...
• [ ] All tests: make test_all
• [ ] LocalNet: verify a LocalNet is still functioning correctly by following the instructions at docs/development/README.md
• [ ] k8s LocalNet: verify a k8s LocalNet is still functioning correctly by following the instructions here
