This commit contains a few fixes for the CI release process.
The base CI image now installs the `jq` binary as it's
required by the promotion process.
The staging script is fixed to use the correct `sed` syntax
for this Linux container, and only consider Gradle as a build
system. This also changes the staging script to correctly
choose the release version depending on the release type.
This commit also adds a `RELEASE_TYPE` parameter to the state
task.
The project build version is moved to a `gradle.properties`
to align with the stage+promote script.
The promote release script is now executable.
This commit adds the CI infrastructure for running builds with
Concourse. This includes:
* a docker image for the CI image (JDK 8 based)
* a set of Concourse pipelines for building, staging and promoting
artifacts
