[sync] : use label selector to pick namespace (#1427)

[zdtsw]

• feat: use label selector to pick namespace

• for clean installation:
  • if user keep using default pre-defined namespace: same as before
  • if user want to use a different namespace: they will need to create project themselves, and add label "opendatahub.io/application-namespace": "true" then install ODH operator and create DSCI by fill in this namespace or install RHOAI and delete auto created DSCI and create DSCI by fill in this namespace
• add more resource kinds into cache due to change use component CR with owns and watches
• add check when start up if we get multiple customized application ns then exit
• add check in DSCI controller: for customized app ns: check if it exists and has label, if not exit as error (do not handle managed case for now since we do not support that yet) force security label on it
• rename createOdhNamespace to createOperatorResource and split into small functions
• add more detail error in DSCI, example: conditions:
  • lastHeartbeatTime: '2025-01-17T15:00:29Z' lastTransitionTime: '2025-01-17T15:00:29Z' message: DSCI must used the same namespace which has opendatahub.io/application-namespace=true label reason: ReconcileFailed status: Unknown or conditions:
  • lastHeartbeatTime: '2025-01-17T15:03:15Z' lastTransitionTime: '2025-01-17T15:03:15Z' message: 'only support max. one namespace with label: opendatahub.io/application-namespace=true' reason: ReconcileFailed status: Unknown
