Simplify CryptoSSLRequestManager using unified futures API

Summary:
This diff unifies the nearly-replicated call paths for ECDSA and RSA
sign request/response/fallback/etc. into one generic futures-based sign API.
Once this is tested, we should be able to remove ~500 lines of code from
CryptoSSLRequestManager

Depends on D3094660
