In this commit both registration & tables lookup go through CatalogManager with respect to the current default  catalog & database. It is not decoupled from Calcite yet. The next step will be to register the CatalogTables built exclusively in the table api rather than converted already to the Calcite's Tables.

This closes #8404

This PR adds support for Hive partitions in HiveCatalog.

This PR creates HiveCatalogFunction class and adds support for Hive function operations in HiveCatalog.

If the consumer can not establish a connection to remote task executor while requesting remote subpartition, which might indicate the remote task executor is not reachable.
We could wrap this connection exception into new proposed PartitionConnectionException which also extends PartitionException, then the job master would decide whether to
restart the upstream region to re-producer partition data.

This closes #8509.

The new proposed PartitionException would cover all the cases of consuming partition failure which causes consumer failed, then JM decides to restart the producer based on this exception.

[FLINK-6227][network] (part 2)Make current PartitionNotFoundException extend PartitionException

This closes #8242.

The current usage of PartitionException is only for describing the RPC of update parttitions failed, so the exception rename would not have any other effects.
In flip1 PartitionException is used for presenting all the cases that indicate to restart the producer while the consumer failed.

It is necessary for flip1 to make sure the PartitionNotFoundException would be setted on the RemoteInputChannel while retriggering partition request,
so a new unit test is added to cover this case.

[hotfix][network] Introduce PartititonRequestClient interface for creating simple client instance in tests

It is necessary for flip1 to make sure the PartitionNotFoundException would be thrown by LocalInputChannel#requestSubpartition if the partition
was not registered in ResultPartitionManager before. So a new unit test is added to cover this case.

It is necessary to make sure the network server would not transform or swallow the PartitionNotFoundException thrown by ResultPartitionManager, so a new unit test
is added for PartitionReuqestServerHandler to cover this case.

It is necessary to make sure PartitionNotFoundException is thrown on producer side for flip1, so some new tests are added to cover the cases
of creating subpartition view via ResultPartitionManager for registered/unregistered partitions.

Add new SchedulerNG stub implementation, which will represents the future
default scheduler.

Add feature toggle to switch between existing scheduler and stub
implementation.

Add ThrowingRestartStrategy to validate that in new scheduling code paths, the
legacy restart strategies are not used.

This closes #8452.

Move SchedulerNG, SchedulerNGFactory, and its implementations to package
org.apache.flink.runtime.scheduler.
