Remove references to Deprecated fields 'queue-size' and 'queue-flush-interval'

When loading "Cache containers" >> "clustered" >> "default(Distributed, Sync, 2 owners )" >> "Configuration" the General tab does not show Field names or their inputs.

This is caused because

$scope.metadata['queue-size']

and

$scope.metadata['queue-flush-interval']

are undefined in configurationSection.js when function $scope.cleanFieldMetadata is called.

I have checked the underlying DMR command, shown below, using the cli and this does not return any fields with those names.

 /profile=clustered/subsystem=datagrid-infinispan/cache-container=clustered:read-resource-description(recursive=true)

This is caused by the following ISPN changes:
