Stop dotgpg from complaining.
Stop dotgpg from complaining.

Without this when I tried to use the secret resolver, I got:

```
Andrews-MacBook-Pro:infrastructure andrewjhumphrey$ sm apply production market-docs
Executing apply on market-docs in us-east-1
error: You must set Dotgpg.password or Dotgpg.interactive. Use --trace to view backtrace
```

spewed at me..

my stack_master.yml had the following relevant (I think) fragment:

```
region_defaults:
  us-east-1:
    secret_file: production.yml.gpg
    tags:
      environment: production
```
