refactor: remove Kardinal Manager yaml file (#33)

We want users and devs deploying Kardinal Manager with the Kardinal CLI
command instead of using kubectl, so we are removing the YAML file for
Kardinal Manager to reinforce this, otherwise we will have conflicts
while deploying Kardinal Manager if there are existing resources
deployed with kubectl.

 ## Deploying Kardinal Manager to local cluster
 
-Configure it by setting the following environment variables:
+You can use tilt deploy and keeping the image hot-reloading:
 
 ```bash
-KARDINAL_MANAGER_CLUSTER_CONFIG_ENDPOINT=http://localhost:8080/tenant/{36e22127-3c9e-4110-aa83-af552cd94b88}/cluster-resources
-KARDINAL_MANAGER_FETCHER_JOB_DURATION_SECONDS=10
-```
-
-or in the `kardinal-manager/deployment/k8s.yaml`:
-
-```yaml
-  env:
-    - name: KARDINAL_MANAGER_CLUSTER_CONFIG_ENDPOINT
-      # This is valid for reaching out the Kardinal Kontrol if this is running on the host
-     value: "http://localhost:8080/tenant/36e22127-3c9e-4110-aa83-af552cd94b88/cluster-resources"
-    - name: KARDINAL_MANAGER_FETCHER_JOB_DURATION_SECONDS
-    value: "10"
+tilt up
 ```
 
-NOTE: you can get your tenant UUID by running any CLI command
+Or you can use the Kardinal CLI to deploy it
 
-You can use tilt deploy and keeping the image hot-reloading:
+Option 1: Using Kloud Kardinal Kontrol
 
 ```bash
-tilt up
+# the Kloud Kontrol will always pull the latest image version from Docker Hub
+kardinal manager deploy kloud-kontrol
 ```
 
-Or manually build it:
+Option 2: Using the local Kardinal Kontrol with Minikube (better for the dev flow)
 
 ```bash
-# First set the docker context to minikube
+# First build the image
+
+# set the docker context to minikube
 eval $(minikube docker-env)
 docker load < $(nix build ./#kardinal-manager-container --no-link --print-out-paths)
-kubectl apply -f kardinal-manager/deployment
+
+# the local-minikube Kontrol will use the image builded
+kardinal manager deploy local-minikube
 ```
