Hot

When a stack fails to create with the reason `Script exited with code 1`, hot will now attempt to run any configured tests anyway. The idea is to gather information about what failed on the resources automation scripts instead of bombing out and deleting the stack entirely. This opens up the ability to pull logs and other files off the failed stack before deletion happens.

A new function has been introduced that will allow a user to consume environment variables within their `tests.yaml`. Example:

yaml
{ get_env: ENV_VAR }


If the variable does not exist, `hot` will exit with a `KeyError`.

Allow a user to pass in `--insecure` when running `hot test`. This will employ the same functionality you would expect from curl when using the -k flag. This should only be used in situations where SSL verification is not possible.

- The `hot docs` has a new default behavior where it will preserve the ordering of keys within a section that will be documented.
- The `hot docs` command now has a `-a`/`--alphabetic` flag that will sort parameters and outputs alphabetically.

Fixes a bug where if a tests file did not have any parameters defined, it would error with:


AttributeError: 'NoneType' object has no attribute 'items'

This release:
- Adds feature that will allow you to pass in CLI overrides for parameters. If a given parameter is not defined in your `tests.yaml`, it will set it, if the parameter does exist in `tests.yaml`, it will override it.
- Updates code to make it more Python 3 compliant. Note: `hot` still only supports Python 2.7
- Added a function to add CircleCI badges in for `hot docs`
