remove actions from examples and add them to the docs, small fixes

docs/actions.md

+## Infrastructure
+The necessary infrastructure for an execution can be defined in the benchmark manifests. The related resources are create *before* an execution is started, and removed *after* an execution is finished.
+
+### Example
+
+```yaml
+  infrastructure:
+    resources:
+      - configMap:
+          name: "example-configmap"
+          files:
+            - "uc1-kstreams-deployment.yaml"
+```
+
+## Action Commands
+Theodolite allows to execute commands on running pods (similar to the `kubectl exec -it <pod-name> -- <command>` command). This commands can be run either before (via so called `beforeActions`) or after (via so called `afterActions`) an experiment is executed.
+
+### Example
+
+```yaml
+# For the system under test
+  sut:
+    resources: ...
+    beforeActions:
+      - selector:
+          pod:
+            matchLabels:
+              app: busybox1
+        exec:
+          command: ["touch", "test-file-sut"]
+          timeoutSeconds: 90
+    afterActions:
+      - selector:
+          pod:
+            matchLabels:
+              app: busybox1
+        exec:
+          command: [ "touch", "test-file-sut-after" ]
+          timeoutSeconds: 90
+
+# analog, for the load generator
+  loadGenerator:
+    resources: ... 
+    beforeActions:
+      - selector:
+          pod:
+            matchLabels:
+              app: busybox1
+        exec:
+          command: ["touch", "test-file-loadGen"]
+          timeoutSeconds: 90
+    afterActions:
+      - selector:
+          pod:
+            matchLabels:
+              app: busybox1
+        exec:
+          command: [ "touch", "test-file-loadGen-after" ]
+          timeoutSeconds: 90
+```
