Feat/OPDATA-6934 nobi ea

[mmcallister-cll]

Closes #OPDATA-6934

Description

Adds Nobi state price EA

Changes

• Added standard plumbing & WsTransport implementation
• Interesting part: NobiTransportManager in src/endpoint/transportManager that controls request routing based on a max number of WS subscriptions per connection and max number of connections per key (see ticket for details)

Steps to Test

1. yarn test nobi
2. with payloads

{
    "data": {
        "endpoint": "price",
        "base": "BTC",
        "quote": "USD"
    }
}

Set MAX_SUBSCRIPTIONS_PER_TRANSPORT sufficiently low (eg: 2) and request other common crypto pairs (eg: ETH/USD, SOL/USD) to see transport rollover

Quality Assurance

• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant infra-k8s configuration file.
• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant adapter-secrets configuration file.
• If a new adapter was made, or a new endpoint was added, update the test-payload.json file with relevant requests.
• The branch naming follows git flow (feature/x, chore/x, release/x, hotfix/x, fix/x) or is created from Jira.
• This is related to a maximum of one Jira story or GitHub issue.
• Types are safe (avoid TypeScript/TSLint features like any and disable, instead use more specific types).
• All code changes have 100% unit and integration test coverage. If testing is not applicable or too difficult to justify doing, the reasoning should be documented explicitly in the PR.
