mitm-software subdomain for Chrome MITM Software interstitial

[lgarron]

For triggering the Chrome MiTM software interstitial in the wild, we've settled that mitm-software.badssl.com with preloaded HSTS should do.

Rough outline for Sasha:

• Create ca-mitm-software.crt and ca-mitm-software.key like we did did for local testing, with a common name like BadSSL MITM Software Test. Look for ca-superfish.crt and ca-superfish.key and place the new files next to them, respectively.
• Create a copy of all the other files/folders with superfish in the name, where superfish is replaced with mitm-software.
  • Replacesuperfish with mitm-software in the contents of these files. The values you're editing should correspond to various copied files youv'e created.
• Copy the superfish section in certs/Makefile with a mitm-software-replaced section.

If something goes wrong, I would start with domains/known-bad/mitm-software.conf and try to track down anything that looks like a broken reference to another file.

Notes for myself:

• Check cert params to make sure there are no incidental error (e.g. SHA-1)
• Adjust index.html font size.
