Marking the bug as invalid. The ironic team came to an agreement that
setting the API version via configuration option shouldn't be supported
anymore in the Nova driver.

Title:
  Ironic: "api_version" configuration option should support microversion

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  The Nova Ironic driver supports setting the API version that it will
  use to when talking to the Ironic API, to do it one should change the
  "api_version" configuration option under the "ironic" section. The
  problem is that, since Ironic supports microversion we can't set a
  version to be "1.8" for e.g, which is a complete valid version for
  Ironic but the "api_version" field is expecting a Int() instead of a
  Float() or Str().

  How to reproduce:

  1- Set the "api_version" under the "ironic" section in nova.conf to
  some float value, i.e 1.8

  2- Restart nova-compute
