Aerogear 7552 service to keycloak

[mikenairn]

• Fix an issue with parsing the operator flags.
• Add log level option:

  operator-sdk up local --operator-flags="--resync=10 --log-level=debug" --namespace shared

• Updates the operator to handle SharedService resources being transformed into Keycloak resources.
