simmilar to [JJB](https://elasticsearch-ci.elastic.co/view/Elasticsearch%20master/).
Macros are not allowed, and each job must be defined in its own file.
Merging of the default configuration is customized so unlike in standard JJB,
it recurses into YML objects.

#### Merging pull requests ####

Due to Guava's nature as a subset of Google's internal codebase which is
automatically synced to the public GitHub repository, we are unable to merge
pull requests directly into the master branch. Instead, once a pull request is
ready for merging, we'll make the appropriate changes in the internal codebase
