Disable Java specific Travis tests for python-sdk branch
Disable Java specific Travis tests for python-sdk branch

python-sdk branch is exclusively used for Python SDK development. This
change disables the Java tests to cut testing time (~2hrs) on Java
tests.

Jenkins will continue to verify Java tests so this should not result in
accidental breakages. (Jenkins tests are considerably faster).

And we will revert these changes when before python-sdk branch graduates
and merged to master.
