Create a deploy/credentials directory for keys.

I'll consider consolidating *all* of our prerequisite credentials

Ultra-special artisinal rax_clb module, take one.
Configure SSL termination and HTTPS redirects.

Only in production for now.

"== 'yes'" was redundant.
Only update SSL attributes that are actually there.
Enable SSL termination on staging, too.

Monitoring alerts on redirection and SSL certs.

We'll alert if the redirection fails, or if the SSL certificate is about to
expire.

Check for SSL credentials in script/deploy.
Store SSL credentials in the secrets files.
Use different variable names for prod/staging.
Use the right YAML multiline thingy.
Change the SSL cert expiration check to 60 days.
