The 2.53 microversion allows listing hypervisors with
details and filtering on a hypervisor_hostname substring
pattern match.
This makes the python API binding HypervisorManager.search
method allow that as well by adding a new 'detailed' boolean
kwarg which defaults to False for backward compatibility for
the /search and /servers routes before 2.53, but allows
searching and getting detailed results back as well.
