Update folder structure for flex java 8

[kappratiksha]

We need to update the structure of flexible folder to reflect apps as per the java version. We need to copy the java8 apps under flexible/java-8.
P.S. Not deleting the files under flexible/ right now as we need to update the documentation to use the flexible/java-8/ apps. There will be a followup PR for cleanup.

LGTM. I verified that all of the changes are under flexible/java-8. https://screenshot.googleplex.com/AhGRVYsVRPkXUAa. There's no feasible way for me to check if they are identical to the existing samples. I would assume you copied them by cp. To be super cautious, you could compare the directory size or number of files/words between the old and new copy.

I used diff to check for the differences: https://screenshot.googleplex.com/7ux9TwYRfFkGySj

Great! Thanks for sharing the diff result.

For problematic region tags, if used in the docs please add the gae_flex_ prefix or remove them completely:

There are 7 possible violations for not having product prefix.
flexible/java-8/errorreporting/src/main/java/com/example/flexible/errorreporting/ErrorReportingExample.java:34, tag flex_error_reporting
flexible/java-8/helloworld/build.gradle:14, tag gradle
flexible/java-8/helloworld/build.gradle:43, tag gretty
flexible/java-8/helloworld/build.gradle:49, tag model
flexible/java-8/memcache/pom.xml:52, tag dependencies
flexible/java-8/memcache/src/main/appengine/app.yaml:8, tag config
flexible/java-8/memcache/src/main/java/com/example/memcache/MemcacheServlet.java:32, tag example

Is this file needed?

[kappratiksha]

I have just copied over the existing projects from the flexible/ folder to flexible/java-8 and this file was already there as a part of #538. I think it is okay to leave it as is since this repository is for samples. wdyt?

[jinglundong]

I would suggest you double check or at least notify the Docs team before changing the region tags. They might be used by the docs to locate the code blocks.

Since this is a copy to a new directory, this shouldn't be an issue until you delete the old duplicates.
