* chore: Update dependency to knative-serving 0.5.1
* chore: Changed deps to released versions where possible
Rebuilt mod deps and vendor dir based on this dependency list
github.com/knative/serving v0.5.
github.com/knative/pkg v0.0.0-20190330001454-aad7a9ad4639
github.com/mitchellh/go-homedir v1.1.0
github.com/spf13/cobra v0.0.3
github.com/spf13/pflag v1.0.3
github.com/spf13/viper v1.3.1
k8s.io/api kubernetes-1.14.1
k8s.io/apimachinery kubernetes-1.14.1
k8s.io/cli-runtime kubernetes-1.14.1
k8s.io/client-go v11.0.0
sigs.k8s.io/yaml v1.1.0
Not sure if all dependencies are required (e.g. is k8s.io/api required
to be specified explicitely or shouldn't we rely on k8s.io/client-go
to bring it this as a transitive dependency which maches always
the cli-runtime's version.
* chore: Update .gitignore to *not* ignore certain vendor files
* chore: Aligned with k8s version from serving 0.5.2
* chore: Run `go mod tidy`
* chore(modules): Update dependencies
