feat: accept registry-scoped certfile and keyfile as credentials

Closes npm#4765
RFC: npm/rfcs#591

While this doesn't directly allow top-level cert/key as credentials (per the
original issue), it's a more targeted/secure approach that accomplishes the
same end-result; the new options are scoped to a specific registry, and the
actual cert/key contents are much less likely to be exposed. See the RFC for
more context.

Depends on:
* npm/npm-registry-fetch#125
* npm/config#69
