TW-344, TW-340: Create Helm chart for SSC and Prov services

- This also includes Liveliness and Readiness checks for the services(TW-341, TW-345)
- Also added Env variables so they can communicate with each other(TW-342, TW-346)

+# A chart can be either an 'application' or a 'library' chart.

+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
