Done changes to values.yaml by changing the version and color

[milansamuel609]

I have done all of these as instructed:

i) Do changes in values.yml by changing the version and color.

ii) Run the python test that is :

python ./tests/test_app.py

iii) To check if the main and canary deployments are in the ratio 80:20 with the given command:

for i in {1..20}; do curl -H "Host: canary-demo.local" localhost:8082; done

iv) Also at last rolling back the changes to normal due to customer complaints about the UI background colors not being easy on the eyes. We can use this commands:

a) To check the revision version:

helm history canary-demo -n canary-demo

b) To roll back to a particular revision version:

helm rollback canary-demo REVISION_NUMBER -n canary-demo
