(feat) add support to secrets (SSM and Secrets Manager)

[hectorgrecco]

Issue #, if available:
We currently have support for fixed environment variables, but not for sensitive data store at SSM or Secrets Manager.

Description of changes:
I've added a parameter named secrets where you can set SECRET_NAME=AWS_ARN value. I've added a Regex to validate the ARN. I did not write tests, so... If someone could write those tests, the community would be happy :)
