Feature: Add template for SealedSecret

[mlepeshkin]

It would be awesome to add support for SealedSecrets (templates and helpers) so we can use them just like unencrypted secrets in the current chart version.

Here’s what it could look like in values.yaml:

sealedSecrets:
  my-secret:
    encryptedData:
      FOO: "encryptedbar"

The template should then create a SealedSecret object using this definition.

We’re planning to add this to our project, and I’m happy to put together a PR to get this feature in.

@mlepeshkin Hi! I have an error when trying to use more then one secret in the list:

sealedSecrets:
  secrets:
    encryptedData:
      APP_KEY: "AgBq8HvylIF7R+...I35H1ZE="
  regcred:
    annotations: 
      sealedsecrets.bitnami.com/cluster-wide: "true"    
    encryptedData:
      .dockerconfigjson: "AgDgc11XN1P9...vcjnoHWcLf4="

Error:

Error: YAML parse error on universal-chart/templates/secret.yml: error converting YAML to JSON: yaml: line 32: could not find expected ':'

Rendered yaml seems broken on annotations and end of a file
