introduce service.annotations map

[marcules]

• make service annotations configurable through value-map service.annotations

Description of the change

This change enables the user of this helm chart to configure additional annotations for the service manifest.

Benefits

Additional annotations on service level can be used by different kubernetes providers to select the type of LoadBalancer that should be provisioned. This is useful if a user wants to only use private load balancers.

Such configurations could be then set through the value-map service.annotations: --set service.annotations.networking\.gke\.io/load-balancer-type="Internal" #gke --set service.annotations.service\.beta\.kubernetes\.io/azure-load-balancer-internal="true" #aks --set service.annotations.service\.beta\.kubernetes\.io/aws-load-balancer-ip-address-type="dualstack" #eks ipv4+ipv6

Possible drawbacks

None that I can think of

Awesome addition 🤩

@dirsigler I think the release action failed because I used the same minor version for both PRs (didn't know which one you'd pull in first) - sorry for that

[dirsigler]

No worries :D Saw both versions but didn't realize the problem. Already opened a PR by myself to bump the minor version again #29
