This change adds the ability to use the k8s (and friends) drivers to create pods with custom specs. This will allow nodepool admins to define labels that create pods with options not otherwise supported by Nodepool, as well as pods with multiple containers. This can be used to implement the versatile sidecar pattern, which, in a system where it is difficult to background a system process (such as a database server or container runtime) is useful to run jobs with such requirements. It is still the case that a single resource is returned to Zuul, so a single pod will be added to the inventory. Therefore, the expectation that it should be possible to shell into the first container in the pod is documented. Change-Id: I4a24a953a61239a8a52c9e7a2b68a7ec779f7a3d
