Enable remote tasks to be run in cluster
Browse files Browse the repository at this point in the history 
By default, we should run builds matching the local architecture
in-cluster to reduce the overhead of provisioning platforms. This will
enable a fully matrixed build for all images using only the remote
builds. This change will require the multi-platform controller to set
the /ssh/host to localhost in order for the builds to run in-cluster.

In a change from the prior behavior, we will now append a sanitized
version of the entire PLATFORM to the image tag upon request. This
behavior is now needs to be explicitly requested.
