The vnf-create and vnfd-create output is hard to read

* The vnf and vnfd create output text contains the "attributes"
    field which is so large that it makes it impossible to format
    the output text so it is readable.

  * Modified the CreateCommand class to provide the ability to
    remove specified fields from the output of the create command

  * Modified the CreateVNF and CreateVNFD classes to specify that
    the "attributes" field should be removed from the output of
    the create command.
