Suggestions to simplify constructor

[bkreider]

1. The "specs" key can be simplified by using a string pointing to your environment file to avoid repeating all of the packages. Unfortunately, the format is not an environment spec but a requirements.txt format. https://conda.github.io/constructor/construct-yaml/#specs

A list of package specifications; e.g. python 2.7*, pyzmq or numpy >=1.8. The specifications are identical in form and purpose to those that would be included in a conda create --file command. Packages may also be specified by an exact URL, e.g., https://repo.anaconda.com/pkgs/main/osx-64/openssl-1.0.2o-h26aff7b_0.tar.bz2. This key can also take a str pointing to a requirements file with the same syntax.

2. Is there a reason to "keep_pkgs" and then use the post_install.sh to remove them? If not, it would be easier to remove the post_install.sh and allow the installer to remove them.
