kamus: GoogleKms encryption fails on 0.6.2.0 (0.6.1.0 works)

Describe the bug Using version 0.6.2.0 with GoogleKms causes the encryptor to fail without an apparent reason when trying to encrypt values with kamus-cli. Same settings work with 0.6.1.0. Tested with 0.6.3.0 as well, same behavior. Feels like it’s because of some changes between 0.6.1.0 and 0.6.2.0.

Note: 0.6.3.0 controller fails to start with the current version of the chart but that might be something for another issue 😃 I’ll look more into it when I’ll have time

Versions used Kamus (API images): 0.6.2.0 Kamus CLI: 0.3.0 Chart version: 0.4.6 KMS provider: GoogleKms Kubernetes flavour and version: v1.15.7-gke.23

To Reproduce Steps to reproduce the behavior:

1. Install the chart with the above versions and with proper GoogleKms config
2. Port-forward into an encryptor pod
3. kamus-cli encrypt --service-account <sa> --namespace <ns> --kamus-url http://localhost:9999 --allow-insecure-url --secret “<shh>”

[info  kamus-cli]: Encryption started...
[info  kamus-cli]: service account: <sa>
[info  kamus-cli]: namespace: <ns>
[warn  kamus-cli]: Auth options were not provided, will try to encrypt without authentication to kamus
[error kamus-cli]: Error while trying to encrypt with kamus: socket hang up

1. encryptor pod exist with error code 139, events show liveness and readiness checks failing as well, no useful logs in the pod while this happening

Expected behavior kamus-cli calls returns the encrypted value after creating the required key in the keyring (as it is working on 0.6.1.0)

If you need any help let me know, curious how C# is lately 😃
