We previously had all python versions of our packages building on a single job, this PR proposes to split up the python versions to separate jobs on Travis. [The dev repo](omnia-md/conda-dev-recipes#81) has had this feature for a while now and I think its worth considering for here. There are up and downsides so I would like some feedback and opinions. Pros: * Reduces odds of a timeout due to multiple versions being built in the same job * Easier debugging of specific versions * Likely faster total build times in linux and *maybe OSX* Cons: * Adds more jobs which must run, jobs may delay each other since Travis has a concurrent job limit * Each job has to pull down the docker image, slower cumulative start time, but can be done in parallel so wall clock will be faster (limited by previous point) * OSX Builds may actually take longer in Wall Clock time because Travis OSX builds are often backlogged due to total global requests. Thoughts and opinions?
