unify resource directory structure

[tzaffi]

Confusing artifact directory hierarchy

Currently the features directory structure looks like:

❯ tree -d
.
├── integration
├── resources
│   ├── generated_responses
│   ├── generated_responses_231
│   ├── generated_responses_unlimited_assets
│   ├── programs
│   ├── stateproof
│   ├── v2algodclient_responsejsons
│   └── v2indexerclient_responsejsons
└── unit
    ├── abi_responsejsons
    ├── v2algodclient_responsejsons
    └── v2indexerclient_responsejsons

In particular the following appear both in resources and unit.

This story asks that no such duplications occur. Ideally, the directories should be unified. Possibly, the directories under unit all removed with resources being the canonical location of artifacts, regardless of whether for unit or integration tests.
