Added support for configuring tls for ingress and additional ingress annotations.

Very simple changes just adding in code to handle a few additional ingress config options.

• ingress.additionalAnnotations: just extra annotations that get appended to the ingress annotations.
• ingress.tlsConfig: optional tls config for ingress.

I'm not sure what is the ideal way to handle eslint tripping on my destructuring assignment operator. I know that destructuring assignment is a somewhat new EMCA standard(EMCA 6/2015), but I'm pretty sure most environments where this code is running it should be valid. So I could:

1. Change the eslint parser config.
2. Change my code to comply with what ever EMCA version is the default for eslint.
