ironic cors don't allow PATCH method

[Jiri Tomasek]

Ironic CORS configuration on undercloud currently does not allow PATCH method. This prevents TripleO UI from updating node https://developer.openstack.org/api-ref/baremetal/#update-node which is used for nodes tagging.

Steps to reproduce:
In TripleO UI navigate to Nodes page, select node and run 'Tag Nodes' action from nodes toolbar kebab dropdown. Browser console registers CORS error.

Expected results: Nodes get tagged correctly.

Steps to fix the issue: Add PATCH to allowed_methods in Ironic CORS configuration in Undercloud installation.
