Feat/OPDATA-4973 debug endpoint

[mmcallister-cll]

Closes #OPDATA-4973

Description

Refactor & adds address-debug endpoint to multi-address-list EA for diagnostic purposes

Changes

• Refactored existing address transport into common functions
• Wrote new endpoint address-debug that bypasses scheduler logic (see ticket for details)

Steps to Test

1. yarn test multi-address-list
2. with payload in ticket comments

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 or update the soak testing blacklist.
• 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.
