BREAKING CHANGE: Removing remote integration feature (#17001)

## Context
The feature has not been maintained for more than a year and was never
officially launched.
This PR removes its code due to the upcoming refactoring of the
sync-metadata that will break its logic if not handled properly and it
would be too costly for the time being.

- remove isRemote from object/field metadata
