Add support for ~/.config/validated-patterns/pattern-uuid

* Pristine environment:
$ make show
helm template common/operator-install/ --name-template common -f values-global.yaml --set main.git.repoURL="https://github.com/hybrid-cloud-patterns/common.git" --set main.git.revision=vp-paths
---
apiVersion: gitops.hybrid-cloud-patterns.io/v1alpha1
kind: Pattern
metadata:
  name: common
  namespace: openshift-operators
spec:
  clusterGroupName: example
  gitSpec:
    targetRepo: https://github.com/hybrid-cloud-patterns/common.git
    targetRevision: vp-paths
  gitOpsSpec:
    operatorChannel: gitops-1.8
    operatorSource: redhat-operators
  multiSourceConfig:
    enabled: false
...

* Add UUID to the environment

$ echo "vp-team-bandini" >> ~/.config/validated-patterns/pattern-uuid
$ make show
helm template common/operator-install/ --name-template common -f values-global.yaml --set main.git.repoURL="https://github.com/hybrid-cloud-patterns/common.git" --set main.git.revision=vp-paths  --set main.analyticsUUID=vp-team-bandini
