GH-242: Remove jasypt dependency

Fixes https://github.com/spring-projects/spring-integration-samples/issues/242

Since `jasypt` is not compatible with Spring Security and recommendation
is to use BCrypt or NO-OP instead, remove its dependency and appropriate
bean definitions in favor of NO-OP password encoding.
The purpose of this `http-rest` application is out of Spring Security
encoding capabilities
