Change datalake-handler baseOS to integration-

des:
 - less layers
 - user without home, login shell & password
 - general tidy-up
 - add quotes in run.sh for safety

feeder:

 - less layers
 - user without home, login shell & password
 - general tidy-up
 - alpine's find is from busybox and is built without extended regex support.
   grep is used for regex.
 - adjusted regexes to be more precise

Benefits from switching base image over:
* minimal {java11,python} images maintained by integration team
* using currently "blessed by seccom" versions (:latest tag used)
* should limit spread of legal issues across layers
* integration images will be the first to have automated compliance
  documentation
* should limit spread of base layers (contributing to deployment
  footprint - more base layers = more to download, more to store etc...)
