Drop Admin Password From API

[dgoodwin]

This functionality was recently dropped from the installer in favor of using a static user with an auto-generated password.

We need to revendor the installer, adjust our API to match the change in openshift/installer#771, and I suspect we will need to pull out the admin password generated similar to how we upload the admin kubeconfig after an install.

CC @jhernand the installer dropped functionality to let you specify the OpenShift admin password and email, is this workable on your side?

CC @ericavonb as well who has a cool idea that may help if we have issues around not being able to set admin password.

@dgoodwin It is workable for us, we are setting a hard-coded password now. If you change Hive so that it informs us of the password generated by the installer we can take it.
