The previous output required too much parsing to be used in an automated fashion. This change makes that a bit easier, without sacrificing usability.
Note that the output is quite a bit different from heroku. This is purposeful as we do not have the concept of dynos.
Closes#3520
Use `GIT_STRATEGY: none` in `stop_review_app` to make job work after successful
merges and when the branch was deleted.
Without this, the application is not stopped when the branch is deleted on merge as the runner pulls the git repository by default, but cannot find the tree in this moment.

### New Features
- #3511: @josegonzalez Add json output to config:export
### Documentation
- #3510: @josegonzalez Remove SPONSORS doc in favor of OpenCollective
- #3509: @Neamar Missing space in markdown formatting
- #3507: @renestalder Fix GitLab CI examples
This change adds json output as both key/value as well as a list of objects. The former can be used in quick scripting environments, while the latter allows higher-level languages to have a bit more structure around how environment variables are declared. Specifically, systems such as kubernetes understand the latter method, while the former can be used within Nomad job files.
The GitLab CI examples used `$CI_ENVIRONMENT_SLUG` for defining the environment names
of the deploy jobs. But this variable is actually the OUTPUT of setting the environment name,
thus, it tries to reference itself, but does not exist in that moment.
The correct way to set this is to use `$CI_COMMIT_REF_NAME` as based on the documentation
of GitLab's dynamic environments.
With the introduciton of procfile-util, scaling a non-existent process to 0 was disabled. This brings back that functionality, allowing users to scale all processes to 0. This is especially useful when a user has accidentally scaled a non-existent process up, causing deploys to fail without any way to revert outside of manually editing files.
Closes#3428
The `domains` command previously had this functionality, but is deprecated, and thus we should provide an alternative method of presenting the information.
This moves the base image from Xenial to Bionic, which is the latest supported LTS release of Ubuntu. Note that all previous releases of herokuish are no longer supported, and users are encouraged to upgrade where possible.
In the case of upgrades, a 'dokku repo:purge-cache APP' should be called for each app, or built applications may include code linked to non-ABI compatible libraries due to the OS upgrade.
This sort of change is usually performed _only_ during a minor release, but as the window since the release is fairly small, the risk to our users is negligible in comparison to the inability to stay on a maintained herokuish release.
