[IBC] Update IBC identifier logic

[h5law]

Objective

Relayers need to use identifiers to specify clients, connections, channels and ports. Currently the identifiers are generated randomly. However, to aid the relayers they should be semi-structured.

The proposed changes are as follows:

1. Client Identifiers should be prefixed with their client type for consistency with ibc-go

• they should have a unique 8 character suffix matching [0-9a-zA-Z]
• example: 08-wasm-Fj06bZ84

2. Connection Identifiers should be prefixed with connection

• they should have a unique 8 character suffix matching [0-9a-zA-Z]
• example connection-8bvC6762

3. Channel Identifiers should be prefixed with channel

• they should have a unique 8 character suffix matching [0-9a-zA-Z]
• example channel-972309bR

4. Port Identifiers should be chosen depending on their purpose

• example transfer

Goals

• Update the identifier logic to follow the patterns above
• Update the unit tests
• Update any usages of the identifiers in the code to match the new pattern

Deliverable

• Identifier logic is consistent with the patterns above
• All unit tests pass

Non-goals / Non-deliverables

• Change any logic where identifiers are being used outside of making them conform to the new standard

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

Is this the reason some of my xPOKT got stuck on the Cosmos Hub and can not be transferred with Keplr wallets "Advanced IBC Transfer" option. Entering the by transaction given "Source Channel Id" returns with "Client is not for pocket". If not please explain how to retrieve the correct Source Channel Id for IBC transfer?
