Handle google-cloud restructure for auto_prepend_file path (#425)

* Add script to locate the stackdriver prepend file

* Remove unused constant

* Use realpath

* Fix prepend.php filename

* Run integration test of build pipeline with enable_stackdriver_integration: true

* Rename test directory for deployment host name length

* Fix test directory in yaml config

* shorten deploy tag for stackdriver deployment test

* Set the google/cloud version for the build pipeline with stackdriver test
