Fixed JANUS parameters.yml
Refactor: Replaced _OC_\w+_ by __OC_\w+__ because now __OC_ENGINE_USER__ is not a substring __OC_ENGINE_USER_PASSWORD__ (instead of: _OC_ENGINE_USER_ of _OC_ENGINE_USER_PASSWORD_)
Renamed oc_config to oc_config.sh for editor syntax highlighting
Refactor: removed duplicated mkdir of CA_PATH and make sure directory exists before trying to remove files from it.
Bugfix: Composer will install SSP, then put JANUS in it and then find out that it can't continue because it doesn't have parameters.yml, so we make the symlink and then retry installing.
