Data Catalog: add delete fileset Entry sample

[ricardolsmendes]

Fileset operations were added to Data Catalog's API and the client library now supports them. Samples are required to update the official docs.

This change depends on googleapis/nodejs-datacatalog#74 to pass the system tests.

@fhinkel is there a reason we'd put this here and not googleapis/nodejs-datacatalog?

Hi, @JustinBeckwith and @fhinkel,
I discussed with @bcoe a while ago and this is what we agreed so far:

1. the present change should be part of this repository because its main code includes more than one API call and is intended to be referred by Quickstart guides in Data Catalog docs;
2. the same applies to Data Catalog: add create fileset Entry sample #1568;
3. once the quickstart-related changes have been merged, we should move the samples residing at https://github.com/GoogleCloudPlatform/nodejs-docs-samples/tree/master/datacatalog/cloud-client to googleapis/nodejs-datacatalog, since each of them represents a single API call and would work as smoke tests to the client library as well.

Please let me know your thoughts.

Kind regards,
Ricardo
