Harshavardhana 85f2b74cfd jwt: Cache the bcrypt password hash. (#3526)
Creds don't require secretKeyHash to be calculated
everytime, cache it instead and re-use.

This is an optimization for bcrypt.

Relevant results from the benchmark done locally, negative
value means improvement in this scenario.
