OPDATA-7764: Convert circle transport in por-address-list to subscription transport

[dskloetc]

OPDATA-7764

Description

We need to support pagination for the Circle address list. This can't be done with an HttpTransport so we need to use a custom SubscriptionTransport.

This PR converts the CircleTransport to use a custom SubscriptionTransport. It does not change any functionality. Pagination will be implemented in a subsequent PR.

Changes

1. Change CircleTransport to extend SubscriptionTransport instead of HttpTransport and make corresponding changes.
2. Change the unit test.
3. The integration test still works unchanged.

Steps to Test

yarn test packages/sources/por-address-list

curl --silent -S -X POST http://localhost:8081 -H 'Content-Type: application/json' -d '{
  "data": {
    "endpoint": "circle"
  }
}'

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.
