Remove unused manila_share_nodes_count variable
Remove unused manila_share_nodes_count variable

The manila_share_nodes_count variable is defined, but not used
anywhere. In some services this is used for the replica count,
but manila (similar to cinder) has a hard-coded replica count
of 1 and therefore this variable is not needed.
