Handle untranslated tabs more gracefully in discopower-module

We no longer test on HHVM

This commit adds the ability to override the defaults in the generated SP metadata for SLO Location and ACS endpoints. This is necessary for my use case as I have additional ACS endpoints to publish in my metadata beyond the generated ones as well as a custom SLO handler that I need to direct my users to. If unset in the config, it uses the defaults as before.

Stream wrappers were assumed to be relative paths. When using a stream wrapper (e.g. s3://) it was appended to the given base path.
