Worker JNDI and SSL configuration - support for stronger encryption algorithms

Support of stronger encryption algorithms and providers in Worker's JNDI and SSL configuration, e.g. the BouncyCastle library is supported.

Worker has to read properties

security.config_properties.encryptor.algorithm=
security.config_properties.encryptor.providerClassName=

 and use them when decrypting password for JNDI and SSL.

Documentation has to mention the provider jar has to be on worker classpath

DONT FORGET! The encryption of SSL passwords which are put on command line should use this too!
