Handling environment variables that include `=`

[stephenyeargin]

I have an environment variable (in this case, an API key) that is something like abcdeadbeef= (with the trailing =). I store my variables as server configuration inputs in Rightscale (a cloud management provider) and they get passed on as plaintext to Foreman to generate a supervisord configuration file.

In summary:

• Environment variable containing an equals
• Foreman 0.78.0
• Generating a Supervisor configuration file

I've tried a few different ways to store it in Rightscale and it keeps being double-encoded. An example:

Provided configuration	Foreman generates ...
export API_KEY=abcdeadbeef=	export API_KEY="abcdeadbeef\="
export API_KEY="abcdeadbeef="	export API_KEY="abcdeadbeef\="
export API_KEY="abcdeadbeef\="	export API_KEY="abcdeadbeef\\\="

I need Foreman to save it as export API_KEY="abcdeadbeef=". Any tips? It appears to be related to shell_quote, but it may be getting munged before then.

Looks related to #519.
