Introduce remote table entity (#4994)

We will require remote table entity to map distant table name and local
foreign table name.
Introducing the entity:
- new source of truth to know if a table is sync or not
- created synchronously at the same time as metadata and foreign table

Adding a few more changes:
- exception rather than errors so the user can see these
- `pluralize` library that will allow to stop adding `Remote` suffix on
names
