Bosch IoT Things: New sub-resource ‘Who am I’ and certificate-based authentication for HTTP connections

The service update comes with various highlights:

• New sub-resource to retrieve subject IDs aka ‘Who am I’
  You can find the subject IDs for your current authentication, using the Who Am I-REST call. Find the resource in the API docs, at the end of the Policies section.
  See also FAQ > How to find the authorization subject IDs that I can use in policies?
• Certificate-based authentication for HTTP connections
  Your persistent HTTP connection can now authenticate with a certificate. To configure your connection respectively, use the Things dashboard > Connections/Integrations or the API docs. Find an example at client-certificate authentication.

In addition, various minor bugs have also been fixed.
