Document [ironic] auth options for inspector

This change documents configuring inspector for client-side
authentication with a standalone Ironic API service.

Since this documention refers to a keystone auth feature which is
about to be released, requirements and lower-constraints are updated
to reflect the required release (see https://review.opendev.org/737365 ).
