Travis CI and Decentralized Buildkite Pipeline

[kj4ezj]

We have decided to run community builds in Travis CI for EOSIO repositories because Travis provides free CICD infrastructure to open-source projects so, if a community member were to inject malicious code into a pull request, it would compromise Travis instead of Block.one.

We have also decided to decentralize the Buildkite pipeline (move it from eos-buildkite-pipelines back into the repository being tested) to reduce the negative impact of erroneous changes to the pipeline code. By decentralizing the pipeline, such changes will be limited to their own branch.

We also now have Travis CI and Buildkite running the same code.
