> We should add the possibility to transactionally check if a Table parameter 
> is changed before altering the table in the HMS.
> This would provide an alternative, less error-prone and faster way to commit 
> an Iceberg table, as the Iceberg table currently needs to:
> - Create an exclusive lock
> - Get the table metadata to check if the current snapshot is not changed
> - Update the table metadata
> - Release the lock
> After the change these 4 HMS calls could be substituted with a single alter 
> table call.
> Also we could avoid cases where the locks are left hanging by failed processes
