Certain API operations support/require additional header parameters to
be set with the query (i.e. DNS supports `x-auth-all-projects` and
`x-auth-sudo-project-id`). Such supported headers should be known from
the OpenAPI spec, so add them in the CLI operation and correspondingly
set them into the query.
In difference to the `python-designateclient` `x-auth-all-projects` will
not be set by default, it is wrong to assume so. Admin user is expected
to set this parameter in the CLI invocation explicitly.
