Hammer CLI

Attempt to create or update host with parameters fail with

"Could not create the host:
Missing arguments for 'host[host_parameters_attributes][0][parameter_type]'

The reason is in Foreman 1.23 the API changed and parameter_type was added and is required.

Possible fixes:
- consider making the type optional with reasonable default in API. It should unblock the error and save us from incompatible changes in API
- add the default type on Hammer side and deprecate the --parameters option. Add new --typed-parameters that support also the new attributes
