Deprecated features to consider for removal for next major release (3.0.0)

[diverdane]

Is your feature request related to a problem? Please describe.

There are some Conjur OSS Helm chart features that are considered deprecated and should be considered for removal when we are ready to bump to the next major (breaking) release (3.0.0).

Automatic Conjur account creation should be default

• Change default value of account.create to true

Default to not creating a ClusterRoleBinding

• Remove rbac.create value
• Add rbac.createClusterRole (defaulting to true`)
• Add rbac.createClusterRoleBinding (defaulting to false`)

Create a single Conjur Kubernetes service

• See Issue Eliminate redundant Kubernetes service for Conjur #131, eliminates redundant Kubernetes service
• Remove service.internal.* values
• Remove service.external.* values
• Remove service.singleService. (Single service mode is always assumed.)

Automatic data key creation should become the default

• This feature has not been implemented yet, but for next major release we should
  consider making this the default behavior.

Remove any out-of-date deprecation warnings from NOTES.txt

After any of the above changes are made, any no longer applicable deprecation
warnings should be removed from conjur-oss/templates/NOTES.txt.
