Issue:
conda build is too quiet
When conda build is run with the `--quiet` argument the output is too quiet, information about the created environments is supressed.  This information was included in the output of conda build 3.16.3.

For example:

<details>
<summary>meta.yaml</summary>

``` yaml
package:
  name: foo
  version: 1.0.0

requirements:
  build:
    - zlib
```

</details>

<details>
<summary>conda build 3.17.4 </summary>

```
