Added menu item to create a new flex project (#1501)

* Added 'Google App Engine Flexible Java Project' menu item under the GCP
dropdown and under File->New->Project

* Added FlexFacetPropertyTester

* Added the google as the provider for org.mockito.stubbing. Tests work
again.

* Add test for FlexFacetPropertyTester

* Changes the type for the property tester

* Moved FlexFacetPropertyTester to c.g.c.t.e.util, renamed it to
FacetExistsPropertyTester and made the functionality more general so
that it supports any facet

* Removed dependency of com.google.cloud.tools.eclipse.appengine.flex on
com.google.cloud.tools.eclipse.appengine.ui

* No need to export c.g.c.t.e.appengine.flex

* Updated javadoc

* Moved the declaration of the flex creation wizard in the gcp drop down
from c.g.c.t.e.appengine.ui to c.g.c.t.e.appengine.flex

* Moved dependecies to Imported Packages

* Did not have the correct namespace for AppEngineFlexProjectWizard. Fixed
now

* Fixed text for flex wizard description
