Update foreign table to distant table schema (#5508)

Closes #5069 back-end part

- do not display schemaPendingUpdates status on remote server lists as
this call will become too costly if there are dozens of servers
- (refacto) create foreignTableService

After this is merged we will be able to delete remoteTable's
availableTables column
