Change usage of internal ids for database objects.

[DmitryMaletin]

At the moment provider has a built in logic how to generate and use internal ids for database objects (tables, views etc. )

Example from table:
Generate and assign:

       database := d.Get("database").(string)
       schema := d.Get("schema").(string)
       name := d.Get("name").(string)

	tableID := &tableID{
		DatabaseName: database,
		SchemaName:   schema,
		TableName:    name,
	}
	dataIDInput, err := tableID.String()
	if err != nil {
		return err
	}
	d.SetId(dataIDInput)

Then in schema.ReadFunc it used like that:

        tableID, err := tableIDFromString(d.Id())
        if err != nil {
                return err
        }
        builder := snowflake.NewTableBuilder(tableID.TableName, tableID.DatabaseName, tableID.SchemaName)

Such approach blocks an interesting scenario when database can be cloned altogether
with state file copying and then use plan and apply only recent changes.
