[alias-server] [p9] Refactor functions to accept constants as input params

Summary:
T2922

Depends on D13084

Since there are no secrets in config.js, start including it in the repo. Refactor functions in alias.js to accept alias constants as input params. This will allow unit tests to be created and preserved for test registration addresses and fee structures (and the production registration address and fee structure).

Test Plan: npm test and all pass
