Variables inside secret files are not interpolated

[FabioNappi]

Describe the bug
MLP does not interpolate variables when they are used inside a secret file.

E.g.

{
  "aKey": "{{VAR_TO_BE_INTERPOLATED}}"
}

Expected behavior
I expect that variables are correctly interpolated

To Reproduce
Steps to reproduce the behavior:

1. Add a secret file with interpolated variables in mlp.yaml of a Console project configuration.
2. Deploy
3. Get secret from k8s and notice that variables have not been interpolated

Machine information (please complete the following information):

• Version 1.1.0

Hi, can you please provide an example of the mlp.yaml file?
