Get OCP nodes status sometimes fails during installation, because of an internal timeout

[smolin-de]

Get OCP nodes status sometimes fails during installation, because of this internal timeout:

Error from server (Timeout): the server was unable to return a response in the time allotted, 
but may still be processing the request (get nodes)

The 'get nodes status' function should be improved. Right now the playbook stop on such error.
E.g. A retry would be a better solution to handle such situation.

Here the reported error:
