Use CreateStartScripts for examples 

This makes it easy to run our test client/server without the "magic" of
executing directly from Gradle. This makes it more obvious what code is
being run and prevents confusion due to Gradle "hanging" when starting
the server.

This also fixes build errors when running 'installDist' at the root
project.

grpc Examples grpc Examples
============================================== ==============================================
In order to run the examples simply execute one of the gradle tasks `routeGuideServer`, To build the examples, run in this directory:
`routeGuideClient`, `helloWorldServer`, or `helloWorldClient`.
For example, say you want to play around with the route guide examples. First you want to start
the server and then have the client connect to it and let the good times roll.
Assuming you are in the grpc-java root folder you would first start the route guide server
by running
``` ```
$ ./gradlew :grpc-examples:routeGuideServer $ ../gradlew installDist
``` ```
and in a different terminal window then run the route guide client by typing This creates the scripts `hello-world-server`, `hello-world-client`,
`route-guide-server`, and `route-guide-client` in the
`build/install/grpc-examples/bin/` directory that run the examples. Each
example requires the server to be running before starting the client.
For example, to try the hello world example first run:
``` ```
$ ./gradlew :grpc-examples:routeGuideClient $ ./build/install/grpc-examples/bin/hello-world-server
```
And in a different terminal window run:
```
$ ./build/install/grpc-examples/bin/hello-world-client
``` ```
That's it! That's it!
