def create_topic(**kwargs):
'''
Creates a message router topic.
Allows 'topic_name', 'topic_description', 'txenable', 'replication_case', 'global_mr_url',
and 'useExisting' as optional node properties. If 'topic_name' is not set,
generates a random one.
Sets 'fqtn' in the instance runtime_properties.
Note that 'txenable' is a Message Router flag indicating whether transactions
are enabled on the topic.
Note that 'useExisting' is a flag indicating whether DBCL will use existing topic if
the topic already exists.
