Bug 1575414

When we run environment-get, we need to remove the created_at and updated_at lines, as well as making all the other variables starting with a lower case.

If we don't do this, we hit this BZ 1570315 because the error message is not very explicit.

Our customer believe that the import/export process should be transparent.

This is the format that environment-get should return:

$ grep -oP "^[^\s]+" overcloud.yaml 
name:
description:
variables:
scope:

This patch seems to solve the issue. I was able to to get and update without a hassle:

# diff mistralclient/commands/v2/environments.py mistralclient/commands/v2/environments.py.orig
