Fix #14

Let's stick to the convention for binaries without the suffix -install.

@alegrey91 I saw a bug we got on master branch when installing with Helm:

1.6537308490105534e+09  ERROR   controller.tenantcontrolplane   Reconciler error        {"reconciler group": "kamaji.clastix.io", "reconciler kind": "TenantControlPlane", "name": "tenant-test", "namespace": "kamaji-system", "error": "error updating tenantControlPlane status: TenantControlPlane.kamaji.clastix.io \"tenant-test\" is invalid: [status.kubeadmPhase.addonCoreDNS: Required value, status.kubeadmPhase.addonKubeProxy: Required value]"}

        /go/pkg/mod/sigs.k8s.io/controller-runtime@v0.11.0/pkg/internal/controller/controller.go:227

Let me fix that on master

@prometherion I just increased the timeout to 5 mins

@alegrey91 it's not a matter of timeout, your failing tests are due to #35, please rebase over master since the fix has been merged and force push.

Funky Gallo approves it! 🐓
