Publish SNAPSHOT builds to OJO on commit.

This publishes a new build to:

https://oss.jfrog.org/artifactory/oss-snapshot-local/com/android/volley/volley/

every time a new commit is pushed to the master branch. Other branches
and pull requests are ignored.

Additional cleanup:

-Remove obsolete Maven configuration files.
-Remove direct-to-bintray publishing config, as in the future we will
be promoting SNAPSHOTS rather than publishing directly.
-Update build metadata to reflect move from AOSP to GitHub.
