PRH uses HTTP with basic authentication to communicate with AAI.  Currently, the PRH application configuration (supplied via the values.yaml file for PRH) includes the AAI username, the AAI password, and an HTTP Authorization header that includes a base64-encoded version of the username and password.   In order to supply the correct value for the Authorization header, we currently run a bash script in an init container.  For the Kohn release, we are eliminating the init container that does this.  To support eliminating the init container, the calculation of the Authorization header needs to move into the main PRH container.
