Move XML based Spring configuration to Java

Move XML based Spring configuration to Java

- The original externalised Spring XML-based configuration deployed to:
    /opt/app/spike-service/dynamic/conf/spike-beans.xml
  has been replaced with Spring Java based configuration.
- Event consumer and publisher configuration is now in property files.
  This now allows obfuscation of passwords.
- Bean creation now allows pre-processing the topic properties.
  For example, the password can now be de-obfuscated before it is
  passed into the bean constructor.
