What is the current behavior?

Addresses feature request for X509 mutual authentication/authorization (Resolves #3)

What is the new behavior?

New configuration parameters added to allow kube-native use of the x509 mutual authentication/authorization provided by the database-agent and mongodb-audit-watcher

In addition this PR contains the following changes:

• Fix for PORT not applying to database agent
• Remove explicit storage class and allow default behaviour

Does this introduce a breaking change?

• Yes
• No

There are no breaking changes as these features are only enabled if <service>.mongoTLS.enabled is set to true (which is not the default behaviour)

Other information

All the environment variables that are used to control the new functionality are documented in the READMEs for each chart
