Removing integration tests from travis steps

[algojack]

Due to Travis not being able to handle our builds anymore, we are removing travis integration tests.

[algobarb]

I think we still require the deploys right now for branch =~ /^rel\// AND type != pull_request. The code for deploy stage looks like they have been removed. I thought we would want to keep those in for Darwin builds and Ubuntu builds since Darwin builds are used for releases and Ubuntu builds updates DevNet.
